Question

Solve for x. 3 − 3/4 x = 1/4 x − 7
A) −10
B) −4
C) 4
D) 10

Answer 1

x = 10

Explanation:

`3 - (3)/(4)x = (1)/(4)x - 7`

Start by subtracting 3 to both sides

`-(3)/(4)x = (1)/(4)x-10`

Subtract 1/4x from both sides ( -3/4 - 1/4 ) = - 1

`-x = -10`

Divide both sides by a negativ 1 to get rid of the negative

∴
`x = 10`
