2a-12x if a-6x=65
You asked:
Given \(a - 6 x = 65\) evaluate the expression \(2 a - 12 x\).
MathBot Answer:
\[2 a - 12 x = \left(-1\right) 12 x + 12 x + 130\]
\[a - 6 x = 65\]Solve for $a$: \[a = 6 x + 65\]Substitute $a$ into the given expression: $$\begin{aligned}2 a - 12 x &= \left(-1\right) 12 x + 2 \cdot \left(6 x + 65\right) \\ 2 a - 12 x &= \left(-1\right) 12 x + 12 x + 130\end{aligned}$$
