Answer:
Yes, that is true, and x=45.
Step-by-step explanation:
Yes, that's how you set up the equation I also listed the sets to solve it below:
3x+15=2x+60
-2x. -2x
--------------------
x+15=60
-15 -15
------------------
x=45
You can also plug it in to check your work.
3(45)+15=2(45)+60
135+15=90+60
150=150
3wx^2
Assuming you mean 5wx^2 - 2wx^2. When you have like terms (terms with the exact same variables), combine them by adding or subtracting the coefficients. 5-2 = 3
