Answer 2

Answer:

The value of the expression

$\sf\:3\:(\:1\:-\:x\:)\:+\:2\:(\:1\:+\:x\:)$ is

$\boxed{\red{\sf\:\frac{95}{16}}}$

Step-by-step-explanation:

We have given that $\sf\:x\:=\:-\:\frac{15}{16}$.

We have to find $\sf\:3\:(\:1\:-\:x\:)\:+\:2\:(\:1\:+\:x\:)$

$\therefore$ By substituting

$\sf\:x\:=\:-\:\frac{15}{16}$ in $\sf\:3\:(\:1\:-\:x\:)\:+\:2\:(\:1\:+\:x\:)$,

we get,

$\sf\:3\:(\:1\:-\:x\:)\:+\:2\:(\:1\:+\:x\:)\\\\\implies\sf\:3\:-\:3x\:+\:2\:+\:2x\\\\\implies\sf\:3\:+\:2\:-\:3x\:+\:2x\\\\\implies\sf\:5\:-\:x\\\\\implies\sf\:5\:-\:(\:-\:\frac{15}{16}\:)\\\\\implies\sf\:5\:+\:\frac{15}{16}\\\\\implies\sf\:\dfrac{80\:+\:15}{16}\\\\\implies\boxed{\red{\sf\:\frac{95}{16}}}$

Additional Information:

1. Substitution of the value of variable:

When the value of a variable is substituted in the given expression, we get the value of that expression.

2. Method to solve such problems:

1. First solve the expression for the last step.

2. Substitute the value of variable in the last step.

3. Solve the expression and get the value of the expression.
