SOLUTION: f(x)= x-5A / -10X + 2 f(-10)= -15 This is a problem that i can't seem to solve. especially when i plug -15 in for (x) but don't know how to get (a) by it self. Thank

Plugging -15 in for

is the wrong thing to do. You need to plug in -10 and then make the whole thing be equal to -15.

Multiply both sides by 102, then add 10 to both sides, then divide both sides by -5
