Question

Find the solution to each system by the substitution method. Check your answers.

2x - 5y = -1
x - 3y = -3

Answer 1

set the x to the lower equation to the same as the top but with opposite sign... multiply each part of the second by that number. -2(x-3y=-3) will turn into
-2x+6y=6 so your left with -5y=-1
6y=6 these should equal y=5 then input y into each equation and solve them for "x"
