Y=x+2 4x+3y = - 36 system of equation

A) Y=x+2

B) 4x+3y = - 36

we rearrange A) as - x + Y = 2 and multiply it by 4

A) - 4x + 4y = 8 then we add B)

B) 4x + 3y = - 36

7y = - 28

y = - 4

A) - 4 = x + 2

x = - 6

(-6, - 4)

Step-by-step explanation:

Use substitution.

Since y is already isolated, substitute it into the y of: 4x+3y=-36.

You should get: 4x+3 (x+2) = -36

Simplify this and you'll get:

4x+3x+6=-36

Add both of the variables:

7x+6=-36

Add - 6 to both sides, (because there is a - 36 on one side, and a 6 on the other, you have to add a negative to eliminate the 6 whilst adding to the - 36)

7x=-42

Divide both sides by 7:

x=-6

Now substitute this into y=x+2

y=-6+2

y=-4
