Question

Solve the linear equation:

`x + 7 -  (8x)/3 = 17/6 - (5x)/2`

Sum

Solution

`x + 7 - (8x)/3 = 17/6 - (5x)/2`

`(3(x + 7) - 8x)/3 = (17 - 5x xx 3)/6`

`(3x + 21 - 8x)/3 = (17 - 15x)/6`

`(-5x + 21)/3 = (17 - 15x)/6`

6(−5x + 21) = 3(17 − 15x)

−30x + 126 = 51 − 45x

−30x = −45x + 51 − 126

−30x = −45x − 75

−30x + 45x = −75

15x = −75

`x = (-75)/15`

x = −5
