Question

What is 4(m+ 1)-(m-1)=20

Answer 1

`\huge\boxed{\sf x = 5}`

Explanation:

Given equation:

4(m + 1) - (m - 1) = 20

• Distribute

4m + 4 - m + 1 = 20

• Combine like terms

4m - m + 4 + 1 = 20

3x + 5 = 20

• Subtract 5 from both sides

3x = 20 - 5

3x = 15

• Divide both sides by 3

x = 15/3

x = 5
