7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.
7x + 2 = 6x + 2 if and only x = 0.
its pretty easy: 3-2 = 1 so if u multiply 1 x 7x, it equals 7x
8x - 2 = -9 + 7x Subtract 7x from both sides: x - 2 = -9 Add 2 to both sides: x = -7
