4/5+4x=7x+94/5
4/5 + 4x = 7x + 94/5
4/5 + 4x - 7x = 7x + 94/5 - 7x
4/5 - 3x = 94/5
4/5 - 3x - 4/5 = 94/5 - 4/5
-3x = 90/5
-3x / -3 = (90/5) / -3
x = (90/5) * (1/-3) divide the 90 by the -3
x = -30 / 5
x = -6
Check it, check it, check it!
4/5 + 4x = 7x + 94/5
4/5 + 4(-6) = 7(-6) + 94/5
4/5 - 24 = -42 + 94/5
0.8 - 24 = -42 + 18.8
-23.2 = -23.2
