Question

3/4 times (x+25)=10 1/5
what is x?

Answer 1

Answer: x = -57/5 or x = -11 2/5

Explanation:

`\begin{array}{l}(3)/(4)\left(x+25\right)=(51)/(5)\longleftarrow10\ (1)/(5)\\\\4\cdot\ \left((3)/(4)\left(x+25\right)=(51)/(5)\right)\cdot4\\\\3\left(x+25\right)=(204)/(5)\\\\(3\left(x+25\right))/(3)=((204)/(5))/(3)\longrightarrow\ (204)/(5)\cdot(1)/(3)=(68)/(5)\\\\x+25=(68)/(5)\\\\x+25-25=(68)/(5)-25\\\\x=-(57)/(5)\ or\ -11\ (2)/(5)\end{array}\\`
