For this case we must simplify the following expression:
![1,075 (5.25) x-5.25 (0.25) (x-3) =](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4rygh0rs0f9vp44k8lk5hbqi9iiiqq1qq7.png)
So, solving the first parentheses we have:
![5.64375x-1.3125 (x-3) =](https://img.qammunity.org/2020/formulas/mathematics/middle-school/w4wkohpanhg5hivvqz904slaljk3jsr4s3.png)
We have to:
![- * + = -\\- * - = +\\5.64375x-1.3125x + 1.3125 (3) =\\5.64375x-1.3125x + 3.9375 =](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7jlkc32c2iu6s7eoscqk0x4s9tajoa8mk0.png)
We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:
![4.33125x + 3.9375](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pjk53h8eqlpftqtmxlmn59twm5w0i7saus.png)
Finally, the simplified expression is:
![4.33125x + 3.9375](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pjk53h8eqlpftqtmxlmn59twm5w0i7saus.png)
ANswer:
![4.33125x + 3.9375](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pjk53h8eqlpftqtmxlmn59twm5w0i7saus.png)
