Answer:
x = 9
Step-by-step explanation:
you can solve with 2 way. First:
- a( b + c) = ab + ac
- a ( b - c) = ab - ac
- a ( b + c) -d = ab + ac -d
So => 5 ( 4x - 5 ) = 5.4x - 5.5
5.4x - 5.5 = 20x - 25
20x - 25 = 155
20x - 25 + 25 = 155 + 25
20x = 180
x = 9
Second way:
- if [tex]\frac{a}{b} = c[/tex] , a = c.b
- if a.b = c , [tex]a = \frac{c}{b}[/tex] or [tex]b = \frac{c}{a}[/tex]
So: 5 ( 4x-5 ) = 155
(4x -5) = [tex]\frac{155}{5}[/tex]
(4x-5) = 31
4x -5 +5 = 4x +5
4x = 36
x = 9
Hope this helps ^-^
