Answer:
B is the right answer
Step-by-step explanation:
Subtract 14 from each side to get the value of m
21 - 14 = 7 = m
m = 7
you can plug it back into the original equation to see if it fits the solution. if not then you have another solution you need to solve for.
4x2x5=40
7x7=49
40+49=89
So the answer is 89
200
37+3=40
40×5=200
Write that down
Answer: 23
x = 90 - 67
x = 23
