Question

Please help me answer the question ​

Answer 1

7. y = 5x

8. k/3 × 4 + 5 = 18

9. y = 2x + 120

--------------

Explanations:

• if the price of car is x

if the price of house is y

so y=5x

• based on the given conditions, formulate

k/\(3x\(4+\(5=18

• assume: x for chair

y for table

according to the problem

y=2x+120

Answer 2

`(4k)/(3)+5=18`

Explanation:

→ Start of with k being divided by 3

`(k)/(3)`

→ Multiplied by 4

`(k)/(3)*4=(4k)/(3)`

→ Added to 5

`(4k)/(3)+5`

→ The answer is 18

`(4k)/(3)+5=18`
