Question

explain in complete sentences how you would use the substitution method to solve the following system of equations and provide the solution to the system .
x+5y=3
2x+9y=4

Answer 1

put x=3-5y in second equation
and solve it

Answer 2

2(x+5y-3)
2x+10y-6
-- --- --
2 2 2
x = 5y -3

Answer 3

no first you have too multiple the first equation by (2) and the second by (-1) so now you have a positive 2x and a -2x it will look like this
2x+10y=6
=-2x-9y=-4
the 2x cancels out which leaves 1y/1=2/1
y=2 then you just choose which equation you want too substitute y for and solve

Answer 4

and that equal sign was suppose too be a (+) sign sorry
