Answer:
[tex]x = 28[/tex]
Step-by-step explanation:
[tex]50 + (2x) + (3x - 10) = 180[/tex]
[tex]180-50=130[/tex]
[tex](2x) + (3x - 10) = 130[/tex]
[tex]5x - 10 = 130[/tex]
[tex]5x = 130 + 10[/tex]
[tex]5x = 140[/tex]
[tex] \frac{5x}{5} = \frac{140}{5} [/tex]
[tex]x= \frac{140}{5} [/tex]
[tex]x = 28[/tex]
