Question

What is the value of y in the solution to the system of equations? x + y = 1 2x – 3y = –30

Answer 1

X=10 y=20 Good Luck :)

Answer 2

X + y = 1.....multiply by -2
2x - 3y = -30
-----------------
-2x - 2y = -2 (result of multiplying by -2)
2x - 3y = -30
----------------add
-5y = -32
y = -32/-5
y = 32/5 or 6.4 <===
