Question

Solve the equation in the picture.

Answer 1

Answer:

B) 5

Step-by-step explanation:

Multiply both sides by 5

2(10x + 15) = 130

Distributive property

20x + 30 = 130

Subtract both sides by 30

20x = 100

Divide both sides by 20

x = 5

Answer 2

Answer:

Option B). x=5

Step-by-step explanation:

The equation is $\frac{2}{5}(10x+15)=26$

Now we start solving the algebraic expression given

First we multiply both the sides of the equation by 5.

$\frac{2}{5}(10x+15)\times 5=26 \times 5$

$2(10x+15)=26\times 5$

$20x+30=130$

Now we subtract 30 on both the sides of the equation

$(20x+30)-30=130-30$

$20x =100$

Now we divide both the sides by 20

$\frac{20x}{20}=\frac{120}{20}$

x = 5

So the option B) x = 5 is the right answer.
