Sagot :
Step-by-step explanation:
[tex](-\frac{7}{2} z +4)+(\frac{1}{5} z -15)\\\\=-\frac{35}{10} z+4+\frac{2}{10}z -15\\\\=-\frac{33}{10}z -11[/tex]
Step-by-step explanation:
Step 1: Simplify
[tex]=-\frac{7}{2}z+4+\frac{1}{5}z-15[/tex]
Step 2: Factor out common terms
[tex]=z\left(-\frac{7}{2}+\frac{1}{5}\right)+4-1[/tex]
Step 3: Simplify
[tex]=-\frac{33}{10}z+4-15[/tex]
Step 4: Subtract the numbers 4 - 15 = -11
[tex]=-\frac{33}{10}z-11[/tex]
Step 5: Simplify
[tex]=-\frac{33z}{10}-11[/tex]
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:
[tex]=-\frac{33z}{10}-11[/tex]
