Answer:
x = 4.31 and y = -1.23 (to the nearest hundredth).
Step-by-step explanation:
y = 16 - 4x
3x + 4y = 8
Substitute y = 16 - 4x in the second equation:-
3x + 4(16 - 4x) = 8
3x + 64 - 16x = 8
-13x = 8 - 64 = -56
x = -56 / -1 3 = 4.308
Plugging this value into the first equation:-
y = 16 - 4(4.308)
= -1.23
Hi!
I'm not sure how to slove this, but I do know how to solve it ;D
<h3>We can't know the exact value of y, but we can isolate y on one side. First, multiply by z on both sides. </h3>

x + y = 3 * z
<h3>Now subtract x from both sides.</h3>
x - x + y = 3 * z - x
<u>y = 3 * z - x</u>
<h2>The answer is y = 3 * z - x</h2>
Hope this helps! :)
