Question

(ii) 4a - 5b algebraic expression​

Answer 1

Answer:

Simplifying

4a + 5b = 0

Solving

4a + 5b = 0

Solving for variable 'a'.

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

Add '-5b' to each side of the equation.

4a + 5b + -5b = 0 + -5b

Combine like terms: 5b + -5b = 0

4a + 0 = 0 + -5b

4a = 0 + -5b

Remove the zero:

4a = -5b

Divide each side by '4'.

a = -1.25b

Simplifying

a = -1.25b
