Question

Translate the sentence into an equation using n to represent the unknown number. Then solve the equation for n.

"A number subtracted from 46 is -21."

a. 46 minus n = -21. n = 67
b. 46 minus 21 = n. n = 67
c. 46 minus 21 = n. n = 25
d. 46 minus n = -21. n = 75

Answer 1

The equation is 46 - n = -21. Solving for n gives n = 67.

Step-by-step explanation:

The sentence can be translated into the equation: 46 - n = -21. To solve for n, we need to isolate it by performing the opposite operation. Since n is being subtracted, we need to add n to both sides of the equation. This gives us:

46 - n + n = -21 + n

Simplifying, we get 46 = -21 + n. To isolate n, we need to subtract -21 from both sides: 46 - (-21) = -21 + n - (-21)

46 + 21 = 0 + n. Therefore, n = 67.
