help me please? 9 + 2x = x + 96
Get everything with x on the same side: 9 + 2x - x = x - x + 96 (subtract x from both sides)
Simplify/combine: 9 + x = 96
Isolate x on one side: x = 96 - 9 (subtract 9 from both sides)
Solve: x = 87

Hi Vincent!
In order to solve for x, we need to get x on one side of the equation. So, we can do that by subtracting 96 from both sides:
9 + 2x - 96 = x + 96 - 96 (will cancel out on the right side of the equation)
Next, compute 9 - 96 to decrease the amount of terms we have:
9 - 96 = -87, plug back into the equation:
2x - 87 = x
Next, subtract 2x from each side:
2x - 87 - 2x = x - 2x (will cancel out on the left side of the equation)
Combine terms:
-87 = -x (x - 2x = -x because the coefficient in front of x = 1 so 1 - 2 = -1)
Multiply by negative 1 on each side to obtain a positive number:
87 = x
You can plug 87 into each spot where the x is in the original problem to check your answer:
9 + (2*87) = 87 + 96
Let's solve for each side of the equation:
9 + (2*87) = 9 + 174 = 183
87 + 96 = 183
We have the right value for x!!
