Question

How would I break down -2(3y+z)-7z -4(3z+8y)​

Answer 1

Remove parentheses

-6y-2z-7z-12z-32y

Then collect like terms

-38y-21z

Answer 2

-38y -21z

Explanation:

1). -(6y + 2z) - 7z- 4(3z + 8y) {Expand by distributing terms}

2). -(6y + 2z) - 7z - (12z + 32y) {Expand by distributing terms}

3). -6y + 2z - 7z - 12z + 32y {Remove parenthesis}

4). ( -6y - 32y ) + (-2z - 7z - 12z) {Collect like terms}

5). -38y -21z {Simplify}
