Answer 1

help me plz

Answer 2

2/5 (x - 2) = 4x --- distribute through the parenthesis
2/5x - 4/5 = 4x --- if you do not want to mess with fractions, multiply everything by common denominator of 5
2x - 4 = 20x --- subtract 2x from both sides
-4 = 20x - 2x
-4 = 18x -- divide by 18 on both sides
-4/18 = x -- reduce
- 2/9 = x

or with fractions..
2/5 (x - 2) = 4x
2/5x - 4/5 = 4x -- subtract 2/5x
-4/5 = 4x - 2/5x
-4/5 = 20/5x - 2/5x
-4/5 = 18/5x -- now divide by 18/5
(-4/5) / (18/5) = x
-4/5 * 5/18 = x
- 20/90 = x -- reduce
-2/9 = x
