Step-by-step explanation:
x = -4y + 6
Now,
Substituting the value of x on 2x + 9y = 16, we get -.
2(-4y + 6) + 9y = 16
-8y + 12 + 9y = 16
y = 16 - 12
<h3>y = 4</h3>
Now,
Substituting the value of y on 2x + 9y = 16, we get -
2x + 9(4) = 16
2x = 16 - 36
2x = -20
<h3>x = -10</h3>
Hence,
The value of x is -10 and y is 4.
