Question

Y=2x+5;x+2y=10

What is the answer using substitution PLEASE

Answer 1

x = 0 and y = 5

Explanation:

y = 2x + 5

x + 2y = 10

Substitute y = 2x + 5 in x + 2y = 10

x + 2(2x + 5) = 10

x + 4x + 10 = 10

5x = 10 - 10

5x = 0

x = 0/5

x = 0

Substitute x = 0 in x + 2y = 10

0 + 2y = 10

2y = 10

y = 10/2

y = 5
