Question

Find the solution to the system of equations.y=-7x+3 y=-x-3

Answer 1

7/3

Explanation:

-3=-7x+3y

y=7/3+3y

7/3x-1

3x+3/7

=7/3

Answer 2

x = 1; y = -4

Explanation:

y = -7x + 3

y = -x - 3

since y = y then -7x + 3 = -x - 3

-7x + 3 = -x - 3

- 7x + 6 = -x (Because we add 3 to both sides)

x = 7x - 6 (Multiply both sides by -1)

-6x = -6 (Subtract 7x from each side)

x = 1
