21x+7+3x=42

Answer 1

x= 35/24 =1 11/24 ≈1.458333333

Explanation:

21x+7+3x=42

Combine 21x and 3x to get 24x.

24x+7=42

Subtract 7 from both sides.

24x=42−7

Subtract 7 from 42 to get 35.

24x=35

Divide both sides by 24.

x= 35/24

Answer 2

x = 35/24

Detailed explanation:

Hi there! Our task is to solve the equation
`\sf{21x+7+3x=42}`.

First, combine the like terms on the left side:

`\sf{24x+7=42}`

Subtract 7 from each side:

`\sf{24x=42-7}`

`\sf{24x=35}`

Divide each side by 24:

`\sf{x=35/24}`

`
`\bigstar` Therefore, x = 35/24.
