Question

Which equation shows the substitution method being used to solve the system of linear equations?

x + y = 6
x = y + 2

Answer 1

Hi :)
So we have 2 equations
x + y = 6 <---equation 1
x = y + 2 <---equation 2
We know what x equals so we plug equation 2 into equation 1
\[\huge~\rm~y+2+y=6\]Can you solve for y? :)

Answer 2

2

Answer 3

Good well done :)
now we know the value of y all we need to do is plug that back into equation 2
x = 2+ 2

Answer 4

so a/b/c/d
A.
x = (x – 6) + 2

B.
x + (y + 2) = 6

C.
(y + 2) + y = 6

D.
x + y = y + 2

Answer 5

Oh in that case just look back at the steps i showed you

Answer 6

so c

Answer 7

Correct :)

Answer 8

yay thx
