x = 3, y = -4
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.

273 13+8 = 21 and 13*21 = 273
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13
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.

(2,3)
It works out that: x = 3 and y = 2
273 13+8 = 21 and 13*21 = 273
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
yes it is
basically you asked what -28+21 which equals -7
If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13
x = 3 and y = -4

The answer to 1 over 2x plus 13 equals 9 is x equals -8.
