The third equation is irrelevant.
Sustitution shows that
X = 7/5*B
Beyond that, no idea.
eq(1) -> x=3a-4b
eq(2) -> 2x=a+b
eq(2) -> 2(eq(1))=a+b
-> 6a - 8b = a + b
-> 5a = 9b
since a = 9/5*b, sub into either equation (easier with eq(1))

x equals -1: When you put the numbers into the equation they will
b equals 1:work out. It took me a while to solve this, but I had a lot

x = 3a - 4b
x = b + a / 2
x = c - 5 / a
this is not a math category
