Answer:
1 - 3x = - 35
Step-by-step explanation:
given the equation
[tex]\frac{1-3x}{5}[/tex] = - 7 ( multiply both sides by 5 )
5 × [tex]\frac{1-3x}{5}[/tex] = 5 × - 7 , that is
1 - 3x = - 35
-----------------
To solve the equation, subtract 1 from both sides
1 - 1 - 3x = - 35 - 1 , that is
- 3x = - 36 ( divide both sides by - 3 )
[tex]\frac{-3}{-3}[/tex] x = [tex]\frac{-36}{-3}[/tex] , that is
x = 12
