Question

Select the equations that have the solution m = 19. Mark all that apply. A m − 4 = 15 B 16 = m − 3 C 4 = m − 15 D 3 + m = 23

Answer 1

Answer:

A, B, C

Step-by-step explanation:

Answer 2

Answer:

A, B, C

Step-by-step explanation:

A) m- 4 = 15

Substitute value of m in equation: 19-4 = 15

See if the equation is true: 19-4 is 15 APPLIES

B) 16 = m-3

Substitute: 16 = 19-3

Is it true?: 19 - 3 is 16 APPLIES

C) 4 = m-15

Substitute: 4 = 19 - 15

True?: 19-5 is 4 APPLIES

D) 3 + m = 23

Substitute: 3 + 19 = 23

True?: 3 + 19 is 22 not 23 DOES NOT APPLY
