3x+7=4x 7=4x-3x 7=x
7-3x = -4x + 13x = 6
3x - 8 = 7 so x = 5
7x = 3 x = 3/7
3x+7=4x-73x=(-)7+4x-4x(-)1x=(-)7________(-)1x=7add (-3x) to each side of equation3x +7 = 4x-3x +3x +7 = 4x -3x0 +7= 1x7=x
In the equation 3x plus 7 equals 13, x is equal to 2.
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
3x - 7 = 5x + 13-2x = 20x = -10
If: 3x-7 = 5x+13 Then: x = -10
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
x=-3
X=10.
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
3x + 7 = 46 is an equation. It can be solved as follows: 3x = 39 so x = 13
(2, 7)
(3, -4)
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
