Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:
To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:
Now, we can substitute this into the first equation. Therefore:
To solve for y, apply the distributive property:
Then, subtract 12 from both sides and you will get:
Then solve for y, by dividing both sides by 10.
Your final answer will be y=1.2
Then, subtract 12 from both sides and you will get:
Then solve for y, by dividing both sides by 10.
Your final answer will be y=1.2
