Answer:
x= 57/2 or 28.5
Step-by-step explanation:
2x + 123 = 180
2x = 180 - 123
2x = 57
x = 57/2 (fraction form) or 28.5 (decimal form)
[tex]x +26 + 97 + x = 180 \\ collecting \: like \: terms \\ x + x + 26 + 97 = 180 \\ 2x + 123 = 180 \\ 2x = 180 - 123 \\ 2x = 57 \\ x = \frac{57}{2} \\ x = 28.5[/tex]
