Question

7a-3b+5a-6b full solution for brainlist​

Answer 1

Answer:

Simplifying

7a + -3b + 5a + 6b = 0

Reorder the terms:

7a + 5a + -3b + 6b = 0

Combine like terms: 7a + 5a = 12a

12a + -3b + 6b = 0

Combine like terms: -3b + 6b = 3b

12a + 3b = 0

Solving

12a + 3b = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3b' to each side of the equation.

12a + 3b + -3b = 0 + -3b

Combine like terms: 3b + -3b = 0

12a + 0 = 0 + -3b

12a = 0 + -3b

Remove the zero:

12a = -3b

Divide each side by '12'.

a = -0.25b

Simplifying

a = -0.25b

Answer 2

Answer:

7a-3b+5a-6b = 7a+5a-3b-6b

= 12a - 9b

9b = 12a

9/12= a/b

hence, 3/4 = a/b
