Answer: B
Explanation
3x + y = 15
2x + 2y = 6
To solve this equation, we want to start by solving 3x + y = 15 for y
3x + y = 15
y = -3x + 15
Then we are going to substitute that for y in 2x + 2y = 6 (I hope you know what substitute mean)
2x + 2y = 6
2x + 2(-3x + 15) = 6
2x - 6x + 30 = 6
-4x = 6 - 30
-4x = -24
Divide both sides by -4
-4x/-4 = -24/-4
x = 6
Now substitute 6 for x in y = -3x + 15
y = -3x + 15
y = -3(6) + 15
y = -18 + 15
y = -3
Thus,
The answer is B (6, -3)
