Question

Could you please check my answer for me? Use substitution to solve the system of equations:Y=3x+5Y=-2xMy answer: x=-1Y=-2

Answer 1

Answer

x = -1

y = 2

Explanation

The system of equations include

y = 3x + 5

y = -2x

Substituting the value for y in the second equation into the first equation, we have

y = -2x

y = 3x + 5

-2x = 3x + 5

-2x - 3x = 5

-5x = 5

Divide both sides by -5

(-5x/-5) = (5/-5)

x = -1

We can then solve for y

y = -2x

y = -2 (-1) = 2

Hope this Helps!!!
