Question

X-y=5 and y=11-x in substitution methood​

Answer 1

x=8

y = 3

Explanation:

x-y=5 and y=11-x

Substitute the second equation into the first

x - (11-x) = 5

Distribute the minus sign

x -11+x = 5

Combine like terms

2x-11 =5

Add 11 to each side

2x-11+11=5+11

2x=16

Divide by 2

2x/2 = 16/2

x=8

Now find y

y=11-x

y=11-8

y=3
