We want to factor out the coefficient of the variable term in the given expression.
0.75z - 6.75The coefficient is equal to 0.75. Let's split into factors 0.75z and 6.75. One of the factors should be equal to 0.75.
0.75z&= 0.75* z
6.75&= 0.75* 9
6.75 is divisible by 0.75, so we can factor out 0.75.
