Answer:
x = 50
Step-by-step explanation:
0.6x + 0.4 (100 − x) = 50
Simplify both sides of the equation.
0.6x + 0.4 (100 − x) = 50
0.6x + (0.4)(100) + (0.4)(−x) = 50 (Distribute)
0.6x + 40 + −0.4x = 50
(0.6x + −0.4x) + (40) = 50 (Combine Like Terms)
0.2x + 40 = 50
Subtract 40 from both sides.
0.2x + 40 − 40 = 50 − 40
0.2x = 10
Divide both sides by 0.2.
0.2x/0.2 = 10/0.2
x = 50
Answer:
x=50
Step-by-step explanation:
0.60x + 0.40(100 − x) = 50
Distribute
0.60x + 0.40(100 − x) = 50
.6x +40 -.4x = 50
Combine like terms
.2x +40 = 50
Subtract 40 from each side
.2x +40-40 = 50-40
.2x= 10
Divide each side by .2
.2x/,2 = 10/.2
x= 50
