Question

HELP PLEASE for brainliest!!

Answer 1

-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735

Answer 2

One way you could solve the system of equations of y is using the process of elimination.

-2(5x+2y=7)
-5(-2x+6y=9)

-10x-4y=-14
10x-30y=-45
-------------------
-34y=-59
------ -----
-34 -34
y=1.735

When rounded is y=1.7

The solution for y is 1.7

Have a blessed day! ;)
