Question

In the equation what is the value of x 1/4(x+4x) + 12= 1/2(2-x)+10

Answer 1

`x=-2(2)/(3)`

Explanation:

1/4(x + 4x) + 12 = 1/2(2 - x) + 10

0.25(x + 4x) + 12 = 0.5(2 - x) + 10

0.25x + x + 12 = x - 0.5x + 10

1.25x + 12 = 0.5x + 10

1.25x + 12 - 12 = 0.5x + 10 - 12

1.25x = 0.5x - 2

1.25x - 0.5x = 0.5x - 0.5x - 2

0.75x = - 2

0.75x ÷ 0.75 = - 2 ÷ 0.75

`x=-2(2)/(3)`
