-3x plus y equals -10

Answer 1

-13

Answer 2

-3x + y = -10

Add 3x to each side:

y = 3x - 10

Any pair of numbers will satisfy this equation, as long as the one you call 'y' is 10 less than triple the one you call 'x'.

A few choices:

X = 1, Y = -7
X = 2, Y = -4
X = 3, Y = -1
X = 4, Y = 2
X = 5, Y = 5

etc.
