Question

HELP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

Answer 1

Explanation:

`(-(7)/(2) z +4)+((1)/(5) z -15)\\\\=-(35)/(10) z+4+(2)/(10)z -15\\\\=-(33)/(10)z -11`

Answer 2

Step-by-step explanation:

Step 1: Simplify

`=-(7)/(2)z+4+(1)/(5)z-15`

Step 2: Factor out common terms

`=z\left(-(7)/(2)+(1)/(5)\right)+4-1`

Step 3: Simplify

`=-(33)/(10)z+4-15`

Step 4: Subtract the numbers 4 - 15 = -11

`=-(33)/(10)z-11`

Step 5: Simplify

`=-(33z)/(10)-11`

Explanation in words:

- To solve this equation, the first step is to simplify the equation.

- To solve this equation, the second step is to factor out the common terms in this equation

- To solve this equation, the third step is to simplify the equation from step two.

- To solve this equation, the fourth step is to subtract the numbers 4 - 15 = -11

- To solve this equation, the fifth step is to simplify the equation from step four.

Answer:

`=-(33z)/(10)-11`

Hope this helps.
