Answer:
a. Jake told the negative value of the expression which cannot be equivalent to the original expression.
b. 10 -
g
Explanation:
a. The given expression is:
![$ (-3)/(7)g + 10 $](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ihs18xkq69awjsd0wzkr3x27w8sycw2vpn.png)
Multiplying through out by -, we get:
which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.
b.
![$ -(3)/(7)g + 10 = 10 - (3)/(7)g $](https://img.qammunity.org/2021/formulas/mathematics/middle-school/2m36t0n0sjdltuyr6b5hscw9deeqmojl8q.png)
![$ = (70 - 3g)/(7) $](https://img.qammunity.org/2021/formulas/mathematics/middle-school/d2ji0pb5u5w6f3wxlwwfp19z5jk5ttbvz4.png)
Hence, the answer.
