Question

The value of $x$ satisfying the equation $(x+9)\times 4+(2x+3)\times 5=10$ is $\frac{-41}{14}$.

• A. True
• B. False

Answer 1

Answer: (A)

True

$(x+9)\times 4+(2x+3)\times 5=10$

$\Rightarrow 4x+36+10x+15=10$

$\Rightarrow 14x+51=10$

$\Rightarrow 14x=10-51$

$\Rightarrow 14x=-41$

$\Rightarrow x=\frac{-41}{14}$
