Let U={b, c, d, e, f, g, h} and A={b, f, g, h}. Use the roster method to write the set A'
podryga [215]

The roster method to write the set A' will be {c, d, e}.

<h3>What are Sets?</h3>

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

Let U = {b, c, d, e, f, g, h} and A = {b, f, g, h}.

The roster method to write the set A' will be given as,

A' = U - A

A' = {b, c, d, e, f, g, h} - {b, f, g, h}

A' = {c, d, e}

The roster method to write the set A' will be {c, d, e}.

More about the sets link is given below.

Solve 2.5-3.5x=8-(4x+6)
IRISSAK [1]
2.5-3.5x= 8-(4x+6)
⇒ 2.5-3.5x= 8- 4x -6
⇒ -3.5x+ 4x= 8 -6 -2.5
⇒ 0.5x= -0.5
⇒ x= -0.5/0.5
⇒ x= -1

Final answer: x= -1~

What is 2y+5x-z=4y+6x and im solving for y
kap26 [50]
Simplifying
2y + 5x + -1z = 4y + 6x

Reorder the terms:
5x + 2y + -1z = 4y + 6x

Reorder the terms:
5x + 2y + -1z = 6x + 4y

Solving
5x + 2y + -1z = 6x + 4y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.
5x + 2y + -6x + -1z = 6x + -6x + 4y

Reorder the terms:
5x + -6x + 2y + -1z = 6x + -6x + 4y

Combine like terms: 5x + -6x = -1x
-1x + 2y + -1z = 6x + -6x + 4y

Combine like terms: 6x + -6x = 0
-1x + 2y + -1z = 0 + 4y
-1x + 2y + -1z = 4y

Add '-2y' to each side of the equation.
-1x + 2y + -2y + -1z = 4y + -2y

Combine like terms: 2y + -2y = 0
-1x + 0 + -1z = 4y + -2y
-1x + -1z = 4y + -2y

Combine like terms: 4y + -2y = 2y
-1x + -1z = 2y

Add 'z' to each side of the equation.
-1x + -1z + z = 2y + z

Combine like terms: -1z + z = 0
-1x + 0 = 2y + z
-1x = 2y + z

Divide each side by '-1'.
x = -2y + -1z

Simplifying
x = -2y + -1z
