Chapter 1: Q10. (page 8)

Evaluate each expression if $x = 4, y = - 2,$ and $z = 6$
10. $z - x + y$

Short Answer

Expert verified

Expression $z - x + y$ results into 0.

Step by step solution

- Order for simplification

To evaluate any expression involving more than one operation, follow the below order of operations:

First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
Evaluate the exponents.
Perform Multiplication and division from left to right.
Perform addition and subtraction from left to right.

- Substitute given values

Simplify from left to right.

Subtract x from z, then add resultant with y.

Substitute 4 for x, $- 2$ for y and 6 for z into given expression

$z - x + y = 6 - 4 + (- 2)$

- Simplify 6-4+-2

Follow order of simplification

$6 - 4 = 2$

Then $2 + (- 2) = 0$

Thus, $z - x + y = 0$
