Heeeeeeeeeeeeeeellppppppppp!!!!!!

Use substitution to solve the system of equations.

A. (–28, 5)
B. (2, –28)
C. (2, –5)
D. (11, –8)

Answer 1

the answer is (2,-5)

Answer 2

Hello!

We will put the x value into the second equation and solve below.

2(-3y-13)+2y=-6
-6y-26+2y=-6
-4y-26=-6
-4y=20
y=-5

We will know put our y value into the first equation to find x.

x==-3(-5)-13
x=15-13
x=2

Just to check we will put our two values into the second equation and see if it is true.

4+-10=-6
-6=-6
----------------------------------------------------------

`\left \{ {{x=2} \atop {y=-5}} \right.`

I hope this helps!
