Can someone explain this step by step please

Answer:
2
Step-by-step explanation:
Since x=-2
-2+3y=4
Add 2 on both sides
3y=6
Divide 3 on both sides
y=2
Answer:
x is equal to -2
the equation is x + 3y = 4
so we substitute the value of 'x' which is -2 in equation x + 3 = 4
Step-by-step explanation:
then we move 3y on left side.
then we add 4 + 2 which is 6.
then it will be, y = 6/3
which is 2
therefore we get y = 2
hope this helps you ☺️☺️
