-3.1x + 7 - 7.4x = 1.5x - 6 (x - 2/3)

The answer would be x=1/2

Step-by-step explanation:

Group Like Terms; -3.1x - 7.4x + 7 = 1.5x - 6 ( x - 2/3 )

-10.5x + 7 = 1.5x - 6( x - 2/3 )

Multiply Both Sides by 1; -10.5x + 7 = 1.5x - 6 (2/3) x 10

Refine; -105x + 70 = 15x - 60 ( x - 2/3)

-105x + 70 = -45x + 40

Subtract 70 from both sides; -105x + 70 - 70 = -45x+40-70

Simplify; -105x = -45x - 30

Add 45x to both sides; -105x + 45x = -45x - 30 + 45x

Simplify; -60x = -30

Divide both sides by -60; -60x/-60 = -30 / -60

SIMPLIFY: x = 1/2

I hope this helps! Good Luck and Have a nice day! :]
