In the equation 3x plus 7 equals 13, x is equal to 2.
3+3x+7x=13 3x+7x=10 10x=10 x=1
x=4
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
3x - 7 = 5x + 13-2x = 20x = -10
3x+5 = 2x+13 3x-2x = 13-5 x = 8
In the equation 3x plus 7 equals 13, x is equal to 2.
3+3x+7x=13 3x+7x=10 10x=10 x=1
x=4
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
2x+3y=13 3x-y=3 x=2
3x - 7 = 5x + 13-2x = 20x = -10
y = (13 - 3x)/2 and that cannot be simplified further.
If: 3x-7 = 5x+13 Then: x = -10
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333
x=-3
X=10.
