Question

Solve for a. 1/3(21-3a)=6-a

Answer 1

no solution

Explanation:

Given

`(1)/(3)` (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution
