Let's solve your equation step-by-step.
x(0.5)+(75)(0.3)+(60)(0.2)=80
Step 1: Simplify both sides of the equation.
x(0.5)+(75)(0.3)+(60)(0.2)=80
0.5x+22.5+12=80
(0.5x)+(22.5+12)=80(Combine Like Terms)
0.5x+34.5=80
0.5x+34.5=80
Step 2: Subtract 34.5 from both sides.
0.5x+34.5−34.5=80−34.5
0.5x=45.5
Step 3: Divide both sides by 0.5.
[tex]\frac{0.5x}{0.5} = \frac{45.5}{0.5} = 91[/tex]
So your answer would be x = 91
