Use substitution to solve the system.<br><br> x=3y-8<br> 3x-4y=-9
nadya68 [22]
<span>x=3y-8
3x-4y=-9

We are told that:
</span>x=3y-8

So replace x in 3x-4y=-9 with x=3y-8 like so: 
3(3y-8)-4y=-9 

Start by distributing the 3: 
(3)(3y)+(3)(-8)+-4y=-9
Now you have: 
9y+-24+-4y=-9&#10;
Combine like terms, now you have: 
5y-24=-9&#10;
add 24 to both sides 
5y-24+24=-9+24&#10;
Now you have:
5y=15
Divide both sides by 5 to get: 
y=3 

Now that you know y=3 plug it into: 
x=3y-8
x=3(3)-8
x=1 

Final answer: 
(1,3)

 it doesn't say how to round the answer so you may need to round it
