-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest
Answers
Answer:
[tex] \sf z = - \dfrac{2}{3} [/tex]
Step-by-step explanation:
Solve for z:
[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)
-4(z + 2) = -4z - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8
Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8
-z - 4z = -5z:
[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8
Expand out terms of the left hand side:
[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8
Add 5z to both sides:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8
5z - 5z = 0:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8
5z - 2z = 3z:
[tex] \longrightarrow [/tex] 3z - 6 = -8
Add 6 to both sides:
[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8
6 - 6 = 0:
[tex] \longrightarrow [/tex] 3z = 6 - 8
6 - 8 = -2:
[tex] \longrightarrow [/tex] 3z = -2
Divide both sides of 3z = -2 by 3:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]
[tex] \sf \dfrac{3}{3} = 1 :[/tex]
[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]

Suppose a, b, and c are all negative numbers. How do you find the distance between the points (a,b) and (a,c)?
Choose the correct answer below.
A. Subtract the lesser of |b| and |c| from the greater.
B. Subtract the greater of |b| and |c| from the lesser.
C. Add to |c|.
D. Subtract |b| from |c|.
E. Subtract |c| from |b|.
Answers
Answer:
E
Step-by-step explanation:
Let's say if b = -2 and c = -3
-2-(-3) = 1 that would be the distance between them. If it was D then you would need absolute value.
