Question

Translate the sentence into an equation.

The sum of 4 times a number and 5 is 2.
Use the variable y for the unknown number

Answer 1

4y+5=2

Explanation:

First, replace "a number" with "y"
The sentence becomes: "The sum of 4 times y and 5 is 2"
Replace "is" with the equals sign, "="
The sentence becomes: "The sum of 4 times y and 5 = 2"
Replace "times" with the multiply symbol, " * "
The sentence becomes: "The sum of 4 * y and 5 = 2"
Replace "the sum of ___ and ___" with " ___ + ___"

The sentence becomes: "4*y + 5 = 2".
the " * " isn't needed since 4y implies multiplication already, so you can optionally remove the *

Answer 2

4y + 5 = 2

Explanation:

4y + 5 = 2 Subtract 5 from both sides

4y = -3 Divide both sides by 4

y =
`(-3)/(4)`
