the answer is 3 and here's why 3x-2=7 add 2 to both sides of the equation (3x-2)+2=7+2 simplify 3x=9 divide both sides by 3 3x/3=9/3 simplify x=3
Assuming simplify = factor...x3 - 3x + 2 = (x-1)(x2+x-2)
Collect like terms together: 3x - 7 - 4 - x = (3x - x) + (-7 - 4) = (3 - 1)x + (-11) = 2x - 11
3x^2 + x + 2x^2 = 5x^2 + x
13x+27=3x+32 Reorder 13x-3x=32-27 Simplify 10x=5 Simplify x=5/10 Simplify x=1/2 Answer
y=3x(x+7)^2

Assuming simplify = factor...x3 - 3x + 2 = (x-1)(x2+x-2)
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
Collect like terms together: 3x - 7 - 4 - x = (3x - x) + (-7 - 4) = (3 - 1)x + (-11) = 2x - 11
3x^2 + x + 2x^2 = 5x^2 + x
13x+27=3x+32 Reorder 13x-3x=32-27 Simplify 10x=5 Simplify x=5/10 Simplify x=1/2 Answer
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
First you simplify: 3x=21 Then you divide both sides by 3: x=7
3x - 7 = 2 3x = 9 x = 3
3x - 2 = 19Add 2 to each side:3x = 21Divide each side by 3:x = 7
