Answer 1

$\huge \star \underline \pink{answer}$

2x-3(7-x)= -1

2x-21+3x= -1

5x-21 = -1

5x=21-1

5x=20

x= 20/5

x=4

Answer 2

Answer:

$2x - 3(7 - x) = - 1 \\ \\ = > 2x - 21 + 3x = - 1 \\ \\ = > 5x - 21 = - 1 \\ \\ = > 5x = - 1 + 21 \\ \\ = > 5x = 20 \\ \\ = > x = \frac{20}{5} \\ \\ = > x = 4$

hope u understand ✌
