Answer:
A. (see Step-by-step explanation)
B. (-1, 4)
Step-by-step explanation:
<em>Since both functions are equal to </em><em>y</em><em>, we can set them equal to </em><u><em>each other.</em></u>
-x + 3 = 4x + 8
<em>Add the </em><em>x</em><em> to both sides (because it is negative on the left) and subtract the </em><em>8</em><em> from both sides (because it is positive on the right and we need to isolate the variable).</em>
-5 = 5x
<em>Divide both sides by 5 (because it is being multiplied to the </em><em>x</em><em>) to isolate </em><em>x</em><em>.</em>
x = -1
<em>Next, to solve for </em><em>y</em><em>, we can plug in </em><em>-1</em><em> for </em><em>x</em><em> in either equation from the beginning.</em>
y = -(-1) + 3
y = 1 + 3
y = 4
