Question

Y=x+2 and x+y=8 in substitution method​

Answer 1

Answer:

$y = x + 2 \\ x + y = 8 \\ x + x + 2 = 8 \\ 2x = 8 - 2 = 6 \\ 2x = 6 \\ x = 6 \div 2 = 3 \\ y = x + 2 = 3+ 2 = 5$

Answer 2

Answer

X= 3 y=5

Step-by-step explanation:

y=x+2

x+y=8

plug in (x+2) for y into the equation x+y=8 to get the same variable.

x+(x+2)=8

2x+2=8

2x=6

x=3

plug in x=3 into x+y=8

3+y=8

y=5

Therefore, x=3, y=5
