Answer 1

Solve:3(100 + 2x) = 4(130 + x)Answer: x=110

Explanation:

Answer 2

110

Explanation:

We have the following equation:

`\begin{gathered} 3\cdot\mleft(100+2x\mright)=4\cdot\mleft(130+x\mright) \\ \end{gathered}`

We solve for x:

`\begin{gathered} 300+6x=520+4x \\ 6x-4x=520-300 \\ x=(220)/(2) \\ x=110 \end{gathered}`

The equation is true when x is equal to 100
