Question

3a+9=6a solve the equation​

Answer 1

Step-by-step explanation:

Simplifying 3a + 9 = 6a + -27 Reorder the terms: 9 + 3a = 6a + -27 Reorder the terms: 9 + 3a = -27 + 6a Solving 9 + 3a = -27 + 6a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-6a' to each side of the equation. 9 + 3a + -6a = -27 + 6a + -6a Combine like terms: 3a + -6a = -3a 9 + -3a = -27 + 6a + -6a Combine like terms: 6a + -6a = 0 9 + -3a = -27 + 0 9 + -3a = -27 Add '-9' to each side of the equation. 9 + -9 + -3a = -27 + -9 Combine like terms: 9 + -9 = 0 0 + -3a = -27 + -9 -3a = -27 + -9 Combine like terms: -27 + -9 = -36 -3a = -36 Divide each side by '-3'. a = 12 Simplifying a = 12

Answer 2

3a + 9 = 6a

9 = 6a - 3a

9 = 3a

9/3 = a

a = 3
