Question

Solve the following two equations simultaneously using substitution.
3x+2y=26
x-4y=4

Answer 1

For substitution we need to make x = ... or y = ...
lets take x-4y=4
Rearrange it so that it is in the form x = ...

Answer 2

?

Answer 3

(1)\[3x+2y=26\](2)\[x-4y=4\]
Making (2) explicit for x:\[x=4y+4\]Substituting into (1):\[3(4y+4)+2y=26\]\[12y+12+2y=26\]\[14y=14\]\[y=1\]Substituting into (2):\[x-4(1)=4\]\[x=8\]
