Solve the system of equations
Elden [556K]

Answer:

Step-by-step explanation:

-4x + 2y = -30

-2x + 2y = -10

-4x + 2y = -30

 2x - 2y = 10

-2x = -20

x = 10

-2(10) + 2y = -10

-20 + 2y = -10

2y = 10

y = 5

(10, 5)

algol13

Answer:

31

Step-by-step explanation:

Here the trick is to perform the indicated operations in the correct order.  Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.

Doing the work inside parentheses first:

(3 × 22) ÷ 6 + [28 – (4)2]  =>  (66) ÷ 6 + [28 - 8], or

(66) ÷ 6 + [28 - 8]  =>  11 + [20], or 31
