Solve equations X+2y=12 and 3x-3y=4 in graph and equal values.

Answer 1

I cannot draw the graph into this editor.

Substitution or elimination will get you the answer about equally efficiently.

y=32/9 and x = 44/9

Multiply the 1st equation by3: 3x+6y=36

Subtract the 2nd equation from the first: 9y=32

y=32/9

From the 1st equation x = 12 - 2y, .e. x= 12-(64/9)=44/9
