Question

Find the values of x and y.

= (10x)

= (10y + 20)

= 100

Answer 1

x = 10 and y = 8

Explanation:

100=10x

100= 10y+20

For x, for first equation, we simply solve for x.

10x = 100 => x=100/10

Therefore, x =10

For y, for second equation, simply solve for y.

100= 10y+20 => 10y = 100-20

10y = 80 => y = 8
