You can put this solution on YOUR website! (3X+6)+(2X-11)=90
3X+6+2X-11=90
5X=90+11-6
5X=95
X=95/5
X=19 ANSWER.
PROOF.
3*19+6+2*19-11=90
57+6+38-11=90
90=90
You can put this solution on YOUR website! Well you really dont need the parentheses because there are no multiplication attached to the () so lets remove them for simplicity's sake
3x + 6 + 2x - 11 = 90
Step 1: Combine like terms (for those not familiar in like terms, a like term is where the letters are the same (x is different from y,) and the same exponent ( and x is different from x^2,)
(3x + 2x = 5x)
(6 - 11 = -5)
so your left with this:
5x - 5 = 90
Step 2: Solve for variable
when solving for one variable you have to move everything else away. First I move the -5 by adding 5 to both sides
5x = 95
then you have to divide by 5 because how do you get rid of something that is being multiplied
x = (I know you can divide)
