ANSWER

The solution is (1,-3)

EXPLANATION

The system of Equations are;

x=4+y

and

-10x+6y=-28

We substitute the first equation into the second equation to get:

-10(4 + y)+6y=-28

We expand the parenthesis to get:

-40 - 10y+6y=-28

Group similar terms to get:

- 10y+6y=-28 + 40

Simplify the similar terms to get;

- 4y = 12

Divide both sides -4.

$y = \frac{12}{ - 4}$

y = - 3

We put y=-3 into the first equation to get:

x = 4 + - 3 = 1

Therefore the solution is (1,-3)
