you want to solve for x,
so you have to isolate x on one side by itself
7x-11=17
you have a -11, so you add 11 to both sides.
you get
7x=28
than you have a 7 multiplied by x, you divide both sides by 7
you then have x= 28 divided by 7=4
x=4
you can't it is impossible babe

7x + y = 4y = 4 - 7x
7x+17 = 45 7x = 45-17 7x = 28 x = 4
7x + 2 = 5,6
Subtract by 7x and divide by 2.
7x-3=39 7x=42 x=6
40 -7x = -16 -7x = -16 -40 -7x = -56 x = 8
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
31=7x-11, 31+11=7x, 42/7=x, x=6 :)
x=4 x=0
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
