Question

Solve using the substitution method.
y=x+2
y-x=8

Answer 1

I came up with using y-2 = x , to substitute into 2nd equation ( y - x =8 ) and it doesn't work out...please help me see what I am doing wrong...thanks

Answer 2

y=x+2, (1)
y-x=8 (2) sub (1) into (2)
x+2 - x=8
0=8-2
0=6
double check your prob

Answer 3

ok I will thanks

Answer 4

You have equation 1 which states: y=x+2
Then 2nd equation say:y=x+8 Do you see the problem? They both can not be true.

Answer 5

thats what I was thinking ...thanx , just needed another 'eye' to look at it :)

Answer 6

if the equations are correct the answer is 'no solution'.
