What’s the solution 6x-3y=-3 & -2x+y=4

6x - 3y = -3

-2x + y = 4

In the second equation, add 2x to both sides.

y = 4 + 2x

Now that we have a value for y, we can plug it into the first equation.

6x - 3(4 + 2x) = -3

Distributive property.

6x - 12 - 6x = -3

Combine like terms.

-12 = -3

Add 3 to both sides.

-9 = 0
