Answer 1

10 = 2y + 4
6 = 2y
y = 3

18 = 10 + 2x
8 = 2x
x = 4

Answer 2

`y=3`

Explanation:

Given figure is a rectangle.

In a rectangle , opposite sides are equal

to find out y we equate the opposite sides 10 and 2y+4

`10=2y+4`

Subtract 4 from both sides

`10-4=2y+4-4`

`6= 2y`

Divide both sides by 2

`y=3`
