Answer 1

29

Explanation:

3x+15+2x+20=180

Combine like terms

5x+35=180

Subtract 35 on both sides

5x=145

Divide by 5 on both sides

x=29

Answer 2

29

Explanation:

5x+35=180 cuz 3x+2x, and 15+20

the subtract 35 on both sides, so 5x = 145

x=29

lets check

3(29)+15 = 102

2(29)+20 = 78

102+78 = 180

so x = 29
