Answer:
x = 5
Explanation:
Given
(x - 10) = 18 - 4x - 1 = 17 - 4x ← collecting like terms on right side
Multiply both sides by 5 to clear the fraction, gives
3(x - 10) = 85 - 20x ← distribute left side
3x - 30 = 85 - 20x ( add 20x to both sides )
23x - 30 = 85 ( add 30 to both sides )
23x = 115 ( divide both sides by 23 )
x = 5
