Explanation:
Given:
![(2)/(3)x + 7 = (1)/(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/nrs07ltzcnavixuoxq9oczy897em2l0yej.png)
Required
Equivalent expression without fraction
To do this, we simply multiply through by a common multiple of the denominators in the expression.
The denominators are 2 and 3
![2 = 2,4,6,8,10,..](https://img.qammunity.org/2021/formulas/mathematics/high-school/2bsrvp8d6w4x256lqj38hnc4sdgq64age8.png)
![3 = 3,6,9,12..](https://img.qammunity.org/2021/formulas/mathematics/high-school/h50qbe3hpth15sl70qupnbzvfteqdbxrnn.png)
So, 6 is the least common multiple.
Multiply both sides by 6
![6 * ((2)/(3)x + 7) = (1)/(2) * 6](https://img.qammunity.org/2021/formulas/mathematics/high-school/rktvfue0i6dms35t6aj1ypohbs902iqeb1.png)
![6 *(2)/(3)x + 6*7 = (1)/(2) * 6](https://img.qammunity.org/2021/formulas/mathematics/high-school/tlecyix5zkoa2qlob9ljkzr4unjoibvbc0.png)
![(12)/(3)x + 42 = (6)/(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/1it88gddyllqfl0pk9519co6h1wih5f96z.png)
![4x + 42 = 3](https://img.qammunity.org/2021/formulas/mathematics/high-school/5ueitqjnbjjwx0ln0wcbcs6u0wx2j907z0.png)
Hence, an equivalent expression.
