Mathematical statements with one or more VARIABLES
are called open sentences.

In statement:

4y + 8 = 6y + 3

variable is y

And i have one more question that i need help on

Solve the following equation.
-4y + 8 = 4 (2y - 2) -2 (-16 + 8y)

A. y= -4
B. y= 4
C. y= -2
D. y= -6

Answered by Bosnian
- 4 y + 8 = 4 ( 2 y - 2 ) - 2 ( - 16 + 8 y )

- 4 y + 8 = 4 ∙ 2 y + 4 ∙ ( - 2 ) - 2 ∙ ( - 16 ) - 2 ∙ 8 y

- 4 y + 8 = 8 y - 8 + 32 - 16 y

- 4 y + 8 = 8 y - 16 y - 8 + 32

- 4 y + 8 = - 8 y + 24

Add 8y to both sides

- 4 y + 8 y + 8 = - 8 y + 8 y + 24

4 y + 8 = 24

Subtract 8 to both sides

4 y + 8 - 8 = 24 - 8

4 y = 16

y = 16 / 4 = 4
