This is an example I put a dot where -2 3/4 should be
<u>The answer is 808/99</u>
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
I think the answer would be x=-7
y= 4x-1
y= 3x+6
y= 1x-1+6
y= 1x-7
x=-7
