x + 5y = -12 is not a question, and thus has no answer. This is equivalent to asking "What is the answer to yellow?"
It equals x+5y simplified
(-5, 2)
x=(-5y-1)/3
5y + x = 0 subtract 5y from each side, then x = -5y
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
(6, -4)
51
x + 5y = 10 5y = -x + 10 y = -x/5 + 2 m = -1/5 or .2
5
(20 - x)/5
x = 6, y = -4
(x, y) = (3, 2)
