Answer:
s=40
Step-by-step explanation:
Combine s and 1/2.
150−s/2=120+1/4s
Combine 1/4and s.
150−s/2=120+s/4
Move all terms containing s to the left side of the equation.
150−3s/4=120
Move all terms not containing s to the right side of the equation.
−3s/4=−30
Multiply both sides of the equation by −4/3.
−4/3 x (−3s/4)=−4/3 x−30 => S=40
