Answer:
20x + 13
Step-by-step explanation:
5(4x + 3) - 2
5× 4x + 5×3 - 2
20x + 15 - 2
20x + 13
Answer:
x = 45
Step-by-step explanation:
Well here's what we know:
2x + 45 + x = 180
Solve from there:
3x = 135
x = 45
You can plug it back in to check:
2(45) + 45 + 45 = 180
90 + 80 = 180, so it checks out :)
If n=4 then plug it into the equation.
4-1
3
so your answer is 3
