Question

If a + b = 23 and a= 47 what would B be?​

Answer 1

b = -24

Explanation:

a + b = 23

Substitute 47 for a.

47 + b = 23

Rearrange the equation.

23 - 47 = b

-24 = b

Check your answer by substituting the value you found for b into the equation.

47 + (-24) = 23

Answer 2

B = -24

Explanation:

a + b = 23

Since a = 47

47 + b = 23

Subtract 47 from each side

47 - 47 + b = 23 - 47

Therefore:

B = -24
