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
Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75
