Question

Rearrange the equation so a is the independent variable 9q - 4 = 3r - 6

Answer 1

• 3q + 2/3

Explanation:

• 3r - 6 = 9q - 4
• Add 6 to both sides
• 3r = 9q - 4 + 6
• Add -4 and 6 to get 2
• 3r = 9q + 2
• Divide both sides by 3
• 3r/3= 9q+3 / 3
• Division undoes multiplication
• r = 9q + 2 / 3
• r = 3q + 2/3

Answer 2

Explanation:

`9q - 4 = 3r - 6 \\ 3r = 9q - 4 + 6 \\ 3r = 9q + 2 \\ r = 3q + (2)/(3)`
