3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x + 1 = 13; 2x = 12; x = 6
[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.

If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
X=27
-2x -11y - 13
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
2x-3y=13
3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x + 1 = 13; 2x = 12; x = 6
An equation where x equals 3.
[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.
