Chapter 0.4, Problem 12E

To determine

To solve the expression $\left|2y-15\right|+7$

Answer to Problem 12E

  $28$

Explanation of Solution

Given Information: $x=2,y=-3,z=1$

  $\left|2y-15\right|+7$

Calculation:

Given equation is

  $\left|2y-15\right|+7$

As given, $x=2$ , $y=-3$ and $z=1$ .

Hence putting values of y in the equation-

  $\left|2\times \left(-3\right)-15\right|+7$

Solving brackets -

  $\left|-6-15\right|+7$

So absolute sign always gives a positive sign-

  $\left|-21\right|+7$

So-

  $21+7$

Hence the final answer is,

  $28$
