One solution ! Which is x=-3
        
             
        
        
        
Since x=-3y+5, substitute x for -3y+5. 
2(-3y+5)+8y=4
Distribute. 
-6y+10+8y= 4
2y+10= 4
Subtract 10 on both sides. 
2y=-6
Divide by 2.
y=-3
Plug in y=-3. 
x=-3(-3)+5
x= 9+5
x=14
(14,-3)
We can check this. 
2(14)+8(-3)=4
28-24=4
4=4 <== this works
I hope this helps!

Answer:
15 is 30% of 50
Step-by-step explanation:
We have, 30% × x = 15
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 15 × 100/30
x = 50
If you are using a calculator, simply enter 15×100÷30, which will give you the answer.
