Question

Find the solution of this system of equations

-9x - 2y = -55
6x - 4y = -26
Stere corect over

Answer 1

x = 3.5

y = 11.75

Explanation:

-9x - 2y = -55

6x - 4y = -26

Step 1:

-2(-9x - 2y = -55) → 18x + 4y = 110

Step 2:

18x + 4y = 110

6x - 4y = -26

24x = 84

24 24

x = 3.5

Step 3:

6(3.5) - 4y = -26

21 - 4y = -26

-21 -21

-4y = -47

-4 -4

y = 11.75
