HELP!!

Find the solution of this system of equations
x - y = 4
- 10x + y = -58

Answer 1

Explanation:

given: x-y = 4

x=4+y

given: -10x + y = -58

plug in for x

-10(4 + y) + y = -58

-40 - 10y + y = -58

-9y = -18

y = -18 / -9

y = 2

now plug in 2 for y in the first equation

x-2=4

x=6

There is the solution x=6, y=2 :)
