Answer:
x=1 y=7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
Hi there! :) The answer to your question is 3. First you do parenthesis r=3.
3+7=10, then you do 10*2=20. That is how you solve the problem.
Hope I helped! :)
