Question

Write the word sentence as an equation. Then solve.

The sum of a number y and -3 is –8.
Equation:
Solution: y =
24

Answer 1

The equation is: y + -3 = 8

And y = -5

Explanation:

Sum means addition which means the sum of a number y and -3 is the same as y + -3. So, you would add the =8's to make it an equation.

Answer 2

The equation y + (-3) = -8 can be solved by adding 3 to both sides of the equation. This gives us the solution y = -5.

The word sentence can be written as an equation in the following way:

y + (-3) = -8

To solve this equation, we need to isolate the variable y.

We start by adding 3 to both sides of the equation to eliminate the negative sign in front of the 3:

y + (-3) + 3 = -8 + 3

Simplifying this, we get:

y = -5

So the solution to the equation is y = -5.
