I'll do one for u.\nIn the first,\nMultiplying both sides by x*,we get\nx+3x+2x*=7x*\n4x+2x*=7x*\nMoving 4x and 2x* to the R.H.S.\n5x*-4x+0=0\nThus 5x*-4x=0\nAttempt the others in the same manner.

OK,as the first one is already done,I am doing the rest for you\n4(2x-6)=x+2 =>8x-24=x+2  =>8x-x=2+24  =>7x=26  =>x=26/3=8 2/3  (3) 2(x+5)+1=3(x-1)+4   =>2x+10+1=3x-3+4 =>2x-3x=-3+4-10-1  => -x=-4  =>x=1  (5)x+6=4(4x-1)   =>x+6=16x-4  =>x-16x=-4-6  => -15x=-10  =>x=-10/-15=2/3 [after reducing]

Hint:\nDo a simple substitution u = x-5\nWhich means x = u + 5\n\nYou should get\n\n(2/5)(x-5)^(5/2) + 2(x-5)^(3/2) + C

(x+3)(x^2+2x+4)\n\nStart by taking the first term in the first parenthesis and multiplying it by each term in the second parenthesis:\n\nx*x^2 + x*2x + x*4 = x^3 + 2x^2 + 4x\n\nNow take the second term and multiply it by each term in the second parenthesis:\n\n3*x^2 + 3*2x + 3*4 = 3x^2 + 6x +12\n\nNow add all of that together\n\nx^3 + 2x^2 + 4x + 3x^2 + 6x +12\n\nand combine terms\n\nx^3 + 5x^2 + 10x +12

step 1)   distribute   -3x-3=2x-16+3\nstep 2)   combine like terms   -3x-3=2x-13\nstep 3)   get your x's on one side   -3=5x-13\nstep 4)   get your other numbers on the other side 10=5x\nstep 5)   divide by the number in front of the x  x=2

3x=2x+5 \n\nyou have to isolate x \n\nmake x on one side of the equal sign\n\n3x=2x+5 \nsubtract 2x from both sides\nx=5

easy if that is the question\n2x+3x=5\nsince they have the same variable\nadd them \n5x=5\nthen divide by 5(no. to reduce the variable with 1 as its coefficient) \nx=1\n\nlonger method\n\n2(x)+3(x)=5\nby distributive property we know that (2+3)x=2(x)+3(x)\nthen: \n(2+3)x=5\n(5)x=5 divide by 5 \nx=1

1.\n3x + 6/((x + 1)(x + 2)) Factor 3 out of the top.\n[3(x + 2)]/[(x + 1)(x + 2)] x+2's cancel\n3/(x + 1) <-- This is simplified.\n\nI don't have the energy to do the other ones right now.  :/
