Question

5(x-3) - 7(6-x)= 21-3(8-x)​

Answer 1

Step-by-step explanation:

5(x-3)-7(6-x)=21-3(8-x)

5x-15-42+7x=21-24+3x

5x+7x-15-42=21-24+3x

12x-57=-3+3x

12x-3x-57=-3

9x-57=-3

9x=-3+57

9x=54

x=54/9

x=6

Hope the answer will help uu!!

Answer 2

Question:

$5(x-3) - 7(6-x) = 21 - 3(8-x)$

Answer:

$5(x-3) - 7(6-x) = 21 - 3(8-x)$

= $5x-15 - 42 -7x= 21 - 24 + 3x$

= $-2x - 57 = -3 + 3x$

= $-2x - 3x = - 3 + 57$

= $- x = 54$

= $\blue{ x = - 54}$
