Answer:
x = - 1
Explanation:
Given
(x - 5)(- 3) = 18
Divide both sides by - 3
x - 5 = - 6 ( add 5 to both sides )
OR
distribute the left side by - 3
- 3x + 15 = 18 ( subtract 15 from both sides )
- 3x = 3 ( divide both sides by - 3 )
x = -1
Expand Brackets
( x - 5 ) ( - 3 ) = 18
- 3 x + 15 = 18
(-15 from both sides)
-3 x = 3
(÷ -3 from both sides)
