Answer:
x=3
y=-1
Step-by-step explanation:
first multiply the 2nd row by 2 so you will get
4x-4y=16
4x+2y=10
then subtract the 2nd row from the first row and so you will get
-6y=6
then solve for y in the above equation
y=-1
then substitute y=-1 into any 2 equations .
i picked the first 1
4x-4 × -1=16
then solve for x .
you will get
x=3

We shall have to use distribution here.
The number outside the parenthesis gets distribute with the numbers inside.
This is called distributive property.
We know the distributive property is
a(b+c) = a × b + a ×c
Using this property for
5(4 x+2)
= 5× 4x + 5 × 2
Now 5 times 4x = 20x
5 times 2 = 10
So we get
5(4 x+2) = 20 x + 10
Option A) is the right answer.
