Answer:
To find the absolute value remove abt negative sign in front of a number and to think of all numbers as a positive
Step-by-step explanation:
x - y = -1 ....... 1
3x + 2y = 22 ........ 2
Make x the subject in the first equation
x = -1+y
Substitute this into the second equation
3(-1+y) + 2y = 22
-3 + 3y + 2y = 22
5y = 25
Divide both sides by 5
y = 5
Substitute y = 5 into x = -1+y
x = -1+5
x = 4
x = 4 , y = 5
