Question

Solve the system of equations.

{table ( (7x + 5y = 36)(2x + 5y = 46) )
Group of answer choices

(7, -10)

(-2, 10)

Answer 1

(-2, 10)

Explanation:

(7x + 5y = 36) × -1

(2x + 5y = 46)

---------------------------

-7x - 5y = -36

2x + 5y = 46

----------------------

-5x = 10

÷-5 ÷-5

---------------

x = -2

2x + 5y = 46

2(-2) + 5y = 46

-4 + 5y = 46

+4 +4

-----------------------

5y = 50

÷5 ÷5

---------------

y = 10

x = -2

y = 10

(-2, 10)

I hope this helps!
