what is 2 + 3 (45x-2)    x = 5?

It depends how you break down the equation.\n\nIf you're saying that X = 5 then...\n\nIf something is in brackets then it's treated as a separate sum so for example 3 x (2+2) is the same as 3 x 4.\n\nIf there's no mathematical symbol then multiplication is used, in the above example the equation could have been written as 3(2+2).\n\nIn your equation the first part is 2 + 3 which equals 5.\n\nYour equation now becomes 5 (45x-2)\n\n45x is the same as 45 x 5 which is 225\n\nYour equation now becomes 5 (225-2)\n\n225 - 2 is 223\n\nYour equation now becomes 5 (223) which is the same as 5 x 223 so THE ANSWER TO YOUR EQUATION WOULD BE 1115\n\nBut the equation could also be read as 2 plus 3 lots of 45x minus 2 in which case the answer is 671 but if this were the case the equation should be written as 2(3(45x-2))\n\nIf you're saying that the answer to the equation is 5 then... \n\nAnother way to read the equation is 2 +3 multipliied by (45 times x minus 2) and the whole lot multiplied by x equals 5.  In which case x = 0.356295

X - 2/3 X =  2X - 5\n\n2X - X + 2/3 X =5\n\n5/3 X = 5\n\nX = 3\n\n\n3 exceeds two thirds of 3 (=2) by 1 which is equal to 5 less twice of three (6-5=1)

1) 45-9= 36\n2) 36-9= 27\n3) 27-9= 18\n4) 18-9= 9\n5) 9-9=0\nThere is no remainder so 45/9 = 5 because there were 5 subtractions.

g(x) = 5x - 4\n\nWith x = 2a, we have:\ng(2a) = 5(2a) - 4\ng(2a) = 10a - 4

Let x = the number you are looking for.\n\nSo, 3x + 7 = 52, which is easily solvable for x as follows:\n\n3x + 7 = 52\n\n3x = 45\n\nx = 15\n\n~ ♥ ~

If your question is 2√(x+5)=√(x+45), then:\nStep 1.  Take the square root of both sides.  You'll get 4x+20√(x)+25=x+45\nStep 2.  Move the numbers and variables until √(x) is by itself.  You'll get √(x)=(3x-25)/(-20)\nStep 3.  Square boths sites to get: x=(9x^2 -150x +625)/(40)\nStep 4.  Multiply both sides by 40.  You'll get: 40x=(9x^2 -150x +625)\nStep 5.  Subtract 40x:  0=(9x^2 -190x +625)\nStep 6.  x=17.034 and 4.077

Well if you note:\n\n1    5 = 5 x 3^0\n2    15 = 5 x 3^1\n3    45 = 5 x 3^2\n4    135 = 5 x 3^3\n\nThe formula would be: y = 5 * 3^(x-1)\n\nFor all tables of this format, divide all y values by the y value paired with x = 1 (sometimes x = 0).  For this table, you'd get 1, 3, 9, 27 = 3^0, 3^1, 3^2, 3^3.

Plug in 2 for x to determine this:\n\n3(2) + 5 = 6+5 = 11 ≠ 17\n\nTherefore 2 is not a solution.\n\n~ ♥ ~
