Answer:
B. 3
Step-by-step explanation:
Let's make an equation for this. Our unknown number is x.
x
We are adding 4.
x + 4
Then multiplying by 5.
(x + 4) • 5
It will equal 35.
(x + 4) • 5 = 35
To solve this, divide both sides by 5.
(x + 4) = 7
Now subtract 4 from both sides.
x = 3
This is your answer.
Check this by plugging it back into our original equation.
(x + 4) • 5 = 35
(3 + 4) • 5 = 35
7 • 5 = 35
35 = 35
Your answer is correct.
Hope this helps!

Answer:
(3x + 8) = 50
(5x - 20) = 50
(5x + 4y) = 130
Step-by-step explanation:
3x + 8 = 5x - 20
2x = 28
x = 14
5(14) + 4y + 5(14) - 20 = 180
y = 15
