Multiply 5 by the first parenthesis, multiply the second paren by -1.

5(x+2) - (2x-3)

becomes
5x+10 -2x + 3

5(x+2) - (2x-3)

1) Remove the brackets first
10x+10-2x+3
2) Group terms
10x-2x + 10+3
3) Compute
8x + 13

= 5x + 10 - 2x + 3
= 3x + 13

5(x+2)-(2x-3)=0
5x+10-2x+3=0
3x+13=0
3x=-13
x=-13/3
