Answer:
Exact Form:
x= -1, -3/5
Decimal Form:
x=-1, -0.6
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable
Answer:
x = 1 or x = [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
given
- 10 | 5x - 4 | - 10 = - 20 ( add 10 to both sides )
- 10 | 5x - 4 | = - 10 ( divide both sides by - 10 )
| 5x - 4 | = 1
The absolute value always returns a positive value, however, the expression inside can be positive or negative, hence
5x - 4 = 1 ( add 4 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
OR
5x - 4 = - 1 ( add 4 to both sides )
5x = 3 ( divide both sides by 5 )
x = [tex]\frac{3}{5}[/tex]
Solutions are x = 1, x = [tex]\frac{3}{5}[/tex]
