ANSWER
B. x=3,y=2
EXPLANATION
The given equations are
and
We add the two equations to eliminate y.
This implies that that:
Simplify:
Divide both sides by 2.
We put x=3 into any of the equations to find y.
Let us substitute x=3 into equation (1) to get:
Divide both sides by -3 to get;
The solution is therefore x=,y=2.
Answer:
64
Step-by-step explanation:
1/5 of 80 = 1/5 × 80 = 16
80 - 16 = 64
It would basically be 15-9 and not a negative so those two lines turn it into the opposite
