3x+4 = 2x-3 3x-2x = -3-4 x = -7
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
3x-2 = 2x+3 3x-2x = 3+2 x = 5
2x+3x = 5x
balance the equation 3x-x=20-6 3x-x=2x 20-6=14 2x=14 x=7
5x+8x+3x-2x = 14x
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
3x+5=4-2x+6 5x=4-1 5x=3 x=3/5
Assuming the question is "solve for x", the answer is x=5
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
x = 4 and y = 0
y=16 x= -4
