There is no symbol between 7x and 31. Please resubmit using words eg "plus", "equals" etc.
-7x + 6 + 7x - 2 = 4
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
x=4 x=0
7x=2x-4 5x=-4 x=-4/5
3x+5=7x-11 5=4x-11 4x=16 x=4
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
x=6
7x + 16 = 3x + 4 4x = -12 x = -3
6 = 7x + x First, add 7x and x.6 = 8xNow, divide both sides by 8.6/8 = xSimplify the answer.3/4 = x.
x=4
x = 4
