Answer:
y = -1
x = 9
(9, -1)
Step-by-step explanation:
1) Since "x" equals <em>-4y+5, </em>substitute that into the bottom equation for x: -4y+5+2y=7
2) Combine like terms: -2y+5=7
3) Subtract 5 from both sides: -2y=-2
4) Divide both sides by -2: y=-1
Now you have figured out that <em>y= -1 </em>
1) Substitute <em>-1 </em>for <em>y </em>in the top equation: x=-4(-1)+5
2) Solve: x=4+5
3) x=9
Now you have figured out that <em>x=9 </em>

The final answer is (9, -1)

Answer:
<h2>x = 9 and y = -3 → (9, -3)</h2>
Step-by-step explanation:
[/tex]
Complementary angles --- they add up to 90 degrees
3 x 9 =27
27 - 5 = 22
To recheck
22+5 =27
27/9 = 3
HERE THE EQUATION IS
=> d = 5x+ 5y
=> d = 5(x+y)
Divinding both side by 5
=> d/ 5 = x+y
=> d/5-x = y
=> y = (d- 5x)/5
So the THIRD option is right for your question.
