70=\left(\frac{70\cdot30}{100}\right)+\left(55\cdot\frac{35}{100}\right)+\left(x\cdot\frac{25}{100}\right),x
You asked:
Solve the equation \(70 = \frac{70 \cdot 30}{100} + 55 \cdot \frac{35}{100} + x \cdot \frac{25}{100}\) for the variable \(x\).
MathBot Answer:
The solution is: \[x = 119\]
\[\begin{aligned}70 &= \frac{70 \cdot 30}{100} + 55 \cdot \frac{35}{100} + x \cdot \frac{25}{100}\\70 &= \frac{x}{4} + \frac{161}{4}\\- \frac{x}{4} &= - \frac{119}{4}\\x &= 119\end{aligned}\]
