x+5 = 3x+15
x-3x = 15-5
-2x = 10
x = -5
x=5
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
-3x + 5 = 20 -3x = 15 x = -5
x = 2
-3/5
3x+4=-11 3x=-15 x=-5
x = 27
3x+5= 4x-10+10 +103x+15= 4x-3x -3x15=X
3x + 8 = -7 Therefore, 3x = -15 x = -5
3x + 5 = 20 Subtract '5' from both sides 3x = 15 Divide both sides by '3' x = 5 The answer!!!!!
3x + 5 = 4x - 10Add 10 to each side:3x + 15 = 4xSubtract 3x from each side:15 = x
3x-5=3x+5 There is no solution.
