Solve, y=5 and 3x +2y=-5

x = -5

Step-by-step explanation:

I) Substitute:

3x + 2y = -5

3x + 2(5) = -5

3x + 10 = -5

II) Solve:

3x + 10 = -5

3x = -15 (Subtract 10 from both sides)

x = -5 (Divide both sides by 3)

x = -5

y = 5

Step-by-step explanation:

We are given the system of equations :

3x + 2y = -5

y = 5

This can be solved through the process of substitution, mainly because y in the second equation already has a value in of its own and can be replaced with the y in the first equation. Therefore :

3x + 2y = -5

y = 5

3x + 2(5) = -5

3x + 10 = -5

Solve for x, first by subtracting ten by both sides :

3x = -15

Divide 3 by both sides to isolate x :

x = -5

Now that we have x, we have solved our system of equations, but let's prove it first.

x = -5

y = 5

3(-5) + 2(5) = -5

-15 + 10 = -5

Therefore, our two variables are x = -5 and y = 5

good luck on your studies! : )
