The functions f(x) and g(x) are defined below.

f(x)=-15x+7
g(x)=-14x+3

Using a table of values, determine the solution to the equation f(x) = g(x).

anonymous · Answer

Well, let me try to get someone here who can assist you, I'm not good with these kind of equations, sorry... @agent0smith @maria.alison @allie_bear22 @*amy*

its ok! thanks for trying anyway:)

I'm not going to show you using a table, since i think it's a stupid method, but you can use substitution here

y=-15x+7
y=-14x+3

set the equations equal to each other, solve for x

-15x+7 = -14x+3
