Question

The value of x satisfying the equation $\frac{x+9}{4}+\frac{2x+3}{5}=10$ is 11.

• A. True
• B. False

Answer 1

Answer: (A)

True

$\frac{x+9}{4}+\frac{2x+3}{5}=10$ is the given equation.

We can check if $x=11$ is a solution by substituting this value in the LHS to check whether it is equal to RHS or not

$\frac{(11+9)}{4}+\frac{(22+3)}{5}$
= 5 + 5
= 10

Thus we see that $x=11$ makes LHS = RHS and is the solution of the given equation.
