5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
-4 5x + 2 = -18 0x + -2 = -2 ---------------- 5x + 0 = -20 5x / 5 = -20/5 x = -4
5x plus 3 does equal 3 plus 5x; commutative law.
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
No. No. No. No.
-4 5x + 2 = -18 0x + -2 = -2 ---------------- 5x + 0 = -20 5x / 5 = -20/5 x = -4
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4

-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
5x plus 3 does equal 3 plus 5x; commutative law.
What is the answer to 2x - 5x plus 6.3 equals -14.4?
