First, add 20 and 40. that gives you 60. then, you divide- 420/60. that gives you 7. then multiply 7 by 20, giving you 140, and multiply 7 by 40, giving you 280. then subtract: 280-140
answer: 140

Hopefully, this helps!
If g(x) = 2x + 3 and we want g(-3) then we need to substitute x for -3
g(-3) = 2(-3) + 3
g(-3) = -6 + 3
g(-3) = -3
