So you have the problem 7 + 3x = 5x + 13
you need to get all the x's to one side and all constants "like 7" to the other side.
So from the left side, subtract 7 from that side but then subtract it from the 13 on the other side.
Now you get 3x = 5x + 6
Now subtract the 5x from the right side and from the left side.
Now you get -2x = 6
Divide the -2 from the x and from the 6 on the right side.
Now you get x = -3

How do you solve 3x-4 equals 5x plus 6?
3x-4=5x+6 gives: 2x=-10 which gives x=-5
What is 6 plus 2x equals 5x plus 9?
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
What is 5x plus 9 equals 3x 15?
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
What is -5x plus 13 equals -12?
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
8x - 4 equals -7 plus 5x?
8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1
What is the answer to 3x plus 7 equals 5x-13?
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
3x - 7 equals 5x plus 13?
3x - 7 = 5x + 13-2x = 20x = -10
What does x equal if 3x-7 equals 5x plus 13?
If: 3x-7 = 5x+13 Then: x = -10
What is 7 minus 3x equals 5x plus 13?
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
What is 3x-7 equals 5x plus 13?
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
3x-7 equals 5x plus 13?
x=-3
3x plus 7 equals 5x - 13?
X=10.
How do you figure out 5x plus 49 equals 8x plus 13?
5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12
What is x in 3x-5x plus 10 equals 36?
x = -13
5x plus 2y equals 7 3x - y equals 13?
(3, -4)
7-3x equals 5x plus 13?
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
What is the answer to 3x plus 9 equals 5x minus 4?
3x + 9 = 5x - 43x +13 = 5x13 = 2x13/2 = xso x = 6.5
