5x-2=13 +2 +2 5x=15 x=3
[5x+13]
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
a linear equation solution 5x-37=13 5x=13+37 5x=50 x=10
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3

[5x+13]
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
This is how I learned: -2 + 5x = 13 5x + -2 + 2 = 13 + 2 5x = 15 -- -- 5 5 x = 3 Then check: -2 + 5 x 3 = ? -2 + 15 = ? 13 =13 This is because when you add and subtract integers, adding negative is subtracting. Subtracting negatives is like adding, but the result is negative. So, when you take -2 + 2 it equals 0.
5x-y equals 18 = -13
a linear equation solution 5x-37=13 5x=13+37 5x=50 x=10
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
5x-3=2-8x 5x-3+3=2-8x+3 5x=5-8x 5x+8x=5-8x+8x 13x=5 x=5/13
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
you need to find out what can you multiply by 5 minus 2 will equal 13. so x=3
