Question

How do you simplify `4.3x (a+b) - 2.1y (a+c) - 1.5x (a+b) + 5.4y (a+c)`?

Answer 1

See a solution process below:

Explanation:

First, group like terms:

`4.3x(a + b) - 1.5x(a + b) - 2.1y(a + c) + 5.4y(a + c)`

Next, factor and combine the like terms:

`(4.3x - 1.5x)(a + b) + (- 2.1y + 5.4y)(a + c) =>`

`2.8x(a + b) + 3.3y(a + c)`
