Answer:
By checking it with multiplication
Step-by-step explanation:
You can use multiplication to check your division answer this way.
Do the division problem.
Multiply the quotient times the divisor.
If there is a remainder, add it to the multiplication product.
Compare this answer to the dividend. They should be the same number (630 = 630).
Answer:
z = 7
Step-by-step explanation:
4z - 8 = 20
Add 8 to each side
4z - 8+8 = 20+8
4z = 28
Divide each side by 4
4z/4 = 28/4
z = 7
Given:
1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):

2. Distributive postulate:

The equation is

3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):

4. Subtraction property of equality:
a) subtract 6 from the first equation:

b) subtract 2 from the second equation:

Answer:
We have the value as 3m-7
Step-by-step explanation:
It is given that we have the real number m. Now we are required to find the simplified form or the value of the expression: 
Thus we can write it as:

Here we have to use the property:

So now we have:

So this is the required final value of the expression.
