Ricky, since you have 3 unknowns, you’ll want 3 equations.
Let mE be the measure of E.
let mF be the measure of F
let mG be the measure of G
What are the equations? The first two sentences of the problem:
mE = 4mF
mG = mE -14
and third one says the angles in a triangle add up to 180
mE + mF + mG = 180
With these three equations, an algebra student can solve for each of the three measures.
If you have any questions, please ask.
