Answer:
x= -5
y= 2
Step-by-step explanation:
Consider the first equation. Insert the known values of variables into the equation.
7(−5)+10y=−15
(Multiply 7 and −5 to get −35)
−35+10y=−15
(Add 35 to both sides)
10y=−15+35
(Add −15 and 35 to get 20)
10y=20
(Divide both sides by 10)
y= 20/10
(Divide 20 by 10 to get 2)
y=2
