6X-Y=-4
2X+2Y=15 IF THE = BETWEEN THE X & THE 2 SHOULD BE A + & YOU WANT TO SOLVE THIS SET OF EQUATIONS THEN
6X-Y=-4
2X+2Y=15 NOW WE MULTIPLY THE FIRST EQAUTION BY 2 AND ADD THESE 2 EQUATIONS
12X-2Y=-8
-------------------------
14X=7
X=7/14
X=.5 OR 1/2 SUBSTITUTING .5 FOR X IN THE SECOND EQUATION WE GET
2*.5+2Y=15
1+2Y=15
2Y=15-1
2Y=14
Y=14/2
Y=7
PROOF
6*.5-7=-4
3-7=-4
-4=-4
