Can someone explain how to get x? 5(x−8)=7(x−4)

Apr 10, 2018

$x = - 6$

Explanation:

=$5 \left(x - 8\right) = 7 \left(x - 4\right)$

=$5 x - 40 = 7 x - 28$

=$5 x - 7 x = - 28 + 40$

=$- 2 x = 12$

=$x = - 6$

Check

$5 \left(- 6 - 8\right) = 7 \left(- 6 - 4\right)$

$- 70 = - 70$

Hope this helps!
