Step-by-step explanation:-

Question:-

1. 5 ( 1-x ) = 3x - 10

Answer:-

: $\implies \: 5(1 - x) = 3x - 10$

: $\implies \: 5 - 5x = 3x - 10$

: $\implies \: - 5x - 3x = - 10 - 5$

: $\implies \: - 8x = - 15$

: $\implies \: 8x = 15$

Removing minus from both the sides

$\implies \: x = \dfrac{15}{8}$

Required Answer:-

The required number is x = 15/8.
