Question

Janelle subtracts -4 from a number. the result is 2. what is the number?

a) -6

b) -2

c) 2

d) 6

Answer 1

The number Janelle started with is -2, after she subtracts -4 from it and the result is 2, as represented by the equation x + 4 = 2, which simplifies to x = -2.

Step-by-step explanation:

When Janelle subtracts -4 from a number and the result is 2, we can represent this situation with the equation x - (-4) = 2. To find the number, we reverse the subtraction of a negative number, which becomes addition. The equation simplifies to x + 4 = 2.

Now, to solve for x, we need to subtract 4 from both sides of the equation resulting in x = 2 - 4, which equals -2.

Therefore, the number that Janelle started with is -2, which corresponds to option b.
