Bangjie (8x-50) / 3 - (10x + 40) = 10
(8x-50)/3=10+(10x+40)
(8x-50)/3=10x+50
8x-50=30x+150
22x=-200
x=-100/11
To solve this equation, (8x-50) 3 - (10x + 40) 5 = 10
It's a process
Multiply both sides by 15 at the same time and change the denominator. This is 5 (8x-50) - 3 (10x + 40) = 150. Multiply and then add and subtract each other. That is 10x = 520. X = 52
X = () is the solution of equation 8x = 144
8x=144
X=144÷8
X=18
So x = 18 is the solution of equation 8x = 144
