Question

Determine the missing number in the equation.

The equation 4 times 7 equals 4 times 10 in parentheses minus 4 times blank

Answer 1

The missing number is 3.

Explanation:

1. For the sake of the equation, let's represent the missing number as y. Then write the equation: 4*7=(4*10)-4*y

2. Follow according to the order of operations, then you should get the result of 28=40-4y

3. Swap -4y and 28 in the equations: 4y=40-28 which goes to 4y=12.

4. Find y by dividing the rest of the equation by 4: y=3
