5x + 2 = 22
5x = 22 - 2
5x = 20
5x/5 = 20/5
x=4
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
5x+3=25 5x = 22 (subtract 3 from each side) x = 22/5 (divide both sides by 5)

x = -1.2, y = -3
It is a linear equation in the variable x. You can solve for x using algebra: -5x + 3 = -22 -5x = -25 -x = -5 x = 5
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
5x+3=25 5x = 22 (subtract 3 from each side) x = 22/5 (divide both sides by 5)
