Note the equal sign, what you do to one side, you do to the other side. Isolate the variable z.
First, subtract 3z and add 6/4 to both sides
4z (-3z) - 6/4 (+6/4) = 3z (-3z) + 1 (+6/4)
4z - 3z = 1 + 6/4
Simplify. Note that 1 = 4/4.
z = 4/4 + 6/4
Simplify. Combine like terms
z = 10/4
Simplify. Change the improper fraction into mixed fraction and simplify.
z = 10/4 = 2 2/4 = 2 1/2

<u>Answer:</u>
False
<u>Step-by-step explanation:</u>
The given statement: 'the order in which you perform operations in a numerical expression does not matter' is absolutely false.
The order or sequence in which a mathematical expression is solved does matter a lot. Performing mathematical operations in a different manner will result in different results.
The rule for performing mathematical operation states that a numerical expression should be solved in the following manner:
1. Brackets
2. Of
3. Division
4. Multiplication
5. Addition
6. Subtraction
