Answer:
Option B). x=5
Step-by-step explanation:
The equation is [tex]\frac{2}{5}(10x+15)=26[/tex]
Now we start solving the algebraic expression given
First we multiply both the sides of the equation by 5.
[tex]\frac{2}{5}(10x+15)\times 5=26 \times 5[/tex]
[tex]2(10x+15)=26\times 5[/tex]
[tex]20x+30=130[/tex]
Now we subtract 30 on both the sides of the equation
[tex](20x+30)-30=130-30[/tex]
[tex]20x =100[/tex]
Now we divide both the sides by 20
[tex]\frac{20x}{20}=\frac{120}{20}[/tex]
x = 5
So the option B) x = 5 is the right answer.
