Answer:
y =5
Step-by-step explanation:
x-2y=-8
when x=2
subtitute the value of x in the equation.
→(2)-2y=-8
collect like terms by moving the number without a coefficient or variable
→-2y=-8-2
-2y=-10(reason being that minus +minus is equal to minus. why if you ask again, you owe a debt (-) and you are adding another debt to it )
divide through by coefficient of y which is -2.
-2y÷-2=-10÷-2
y=5
I hope this helps?.
