You would multiply the top one by -4 and the bottom one by +3, if you want to keep y positive.
What do you have to multiply 1/4 by to get to 1?
4
1/2 x - 1/4 y = 7/2
Multiply across by 4:
2x - y = 14
y = 2x -14
Now multiply the second one across by 3 to finish it yourself.
thank yall(:
Well i can't seem to figure out the intersection on my calc. please help.
