=
Multiply both sides by 3
z + 6 =
Multiply both sides by 4
(4)z + 6 = (3)2z Simplify
4z + 24 = 6z Subtract 4z from both sides
24 = 2z Divide both sides by 2
12 = z Flip the sides to make it easier to read
z = 12
Answer: 412.38
Step-by-step explanation: 0.79 x 522
Answer: 31.5
Concept:
When encounter questions that ask for operation on algebraic expressions, using BODMAS or PEMDAS method would be easier. Since this question asked for using BODMAS, then it is:
- Bracket
- Order
- Division
- Multiplication
- Addition
- Subtraction
Solve:
<u>Given</u>
2 × 3 + 45 ÷ 2 - 6 + 9
<u>Simplify by division</u>
=2 × 3 + 22.5 - 6 + 9
<u>Simplify by multiplication</u>
=6 + 22.5 - 6 + 9
<u>Simplify by addition</u>
=28.5 + 9 - 6
=37.5 - 6
<u>Simplify by subtraction</u>
=31.5
Hope this helps!! :)
