3x+3=2x+6 subtract2x from both sides we get x+3=6 x=6-3= 3
3x + 3 = 2x + 6 x + 3 = 6 (subtract 2x from both sides of the equation) x = 3 (subtract 3 from both sides of the equation)
Check 3(3) + 3 = 2(3) + 6 9 + 3 = 6 + 6 12 = 12 (yes)
Check 3(3) + 3 = 2(3) + 6 9 + 3 = 6 + 6 12 = 12 (yes)
3x+3=2x+6
3x-2x=6-3
x=3
3x-2x=6-3
x=3
