Question 320615: Solve the following systems of equations using any method.
( a ) x + 4 y = - 5
2 y + 3 x = 5
( b ) 2x-1/3y=1/3
3(x+1)-2(y-3)=11
( c ) 2.4 x = 2.2 y – 3.2
1.6 x + 1.2 y = 3.2

Sorry, one question per post.
Multiply the second equation by -2 and then add the two equations.
Substitute into either of the original equations:
Hence the solution set is )
