Question

If x/2+x/5=28, then x equals

Answer 1

Answer:

ATQ,

Given equation can be expressed in a linear equation in one variable in which the variable is x.

After expressing it in a linear equation in one variable we can easily find the value of x by solving it as shown below

$\dfrac{x}{2} + \dfrac{x}{5} = 28 \\ \\ \frac{5x + 2x}{10} = 28 \\ \\ 7x = 28 \times 10 \\ \\ 7x = 280 \\ \\ x = \frac{280}{7} \\ \\ \purple{\bold{\boxed{\boxed{x = 40}}}}$

Answer 2

x/2+x/5=28

(taking LCM as 10)

5x+2x/10=28

7x/10=28

7x=28×10

7x=280

x=280÷7

x=40

hope this helps. ❤✌✌
