Question

Solve the equation. Round to the nearest tenth if necessary.
1. 7r-7=2r+18?

2. 2x+12=18-x?

3. 8x-3=15x+18?

4. 6y-6=4y+16?

5. 3(x-4)=5(x+2)? Help

Answer 1

Hey there! You should start out by combining like terms. You can subtract 2r from both sides and add 7 to both sides yes?

Answer 2

5r = 25
r = 5

Answer 3

That was for question 1. It would be a good idea to ask the other questions on another post :)
