Answer:
<h2>r = 6</h2>
Step-by-step explanation:
18 - r = 12 <em>subtract 18 from both sides</em>
18 - 18 - r = 12 - 18
-r = -6 <em>change the signs</em>
r = 6
<em>Check</em>
18 - 6 = 12 <em>CORRECT</em>
A would be the correct answer because the y variable only has a coefficient of 1. So we would solve for y, which would get us y=3x+5, then we would substitute the value in the second equation which would look like -4x+5(3x+5)=58. Hope this helpss. :)
