Step-by-step explanation:
- 3 ( x + 2 ) + 9 + 7x = 4x + 5 - 2
- 3x - 6 + 9 + 7x = 4x + 5 - 2
- 3x + 7x + 9 - 6 = 4x + 5 - 2
4x + 3 = 4x + 3

<h3>The solution is (x, y) = (3, -24)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x - y = 15 -------- eqn 1
y = -8x ------ eqn 2
We have to find solution of (x, y)
We can solve by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
-3x - (-8x) = 15
-3x + 8x = 15
5x = 15
Divide both sides by 5
<h3>x = 3</h3>
Substitute x = 3 in eqn 2
y = -8(3)
<h3>y = -24</h3>
Thus solution is (x, y) = (3, -24)
