Answer:
x=6.8
Step-by-step explanation:
The given equation is
5(2+5x)=180
First expand the bracket to obtain
10+25x=180
Group like terms to obtain
25x=180-10
This implies that,
25x=170
Divide both sides by the coefficient of x
This implies that,
[tex] \frac{25x}{25}= \frac{170}{25} [/tex]
[tex]x=\frac{170}{25}=6.8[/tex]
Hence x=6.8
