You asked:

Simplify the expression: 3(7x−9)−5(3x−10)3 \left(7 x - 9\right) - 5 \left(3 x - 10\right)

MathBot Answer:

Simplified:

3(7x−9)−5(3x−10)=6x+23 3 \left(7 x - 9\right) - 5 \left(3 x - 10\right) = 6 x + 23

3⋅(7x−9)−5⋅(3x−10)=3⋅(7x−9)−15x−50=21x−27−15x−50=21x−27−15x+50=6x+23\begin{aligned}3 \cdot \left(7 x - 9\right) - 5 \cdot \left(3 x - 10\right)&=3 \cdot \left(7 x - 9\right) - 15 x - 50\\&=21 x - 27 - 15 x - 50\\&=21 x - 27 - 15 x + 50\\&=6 x + 23\end{aligned}
