Mathematical statements with one or more VARIABLES
are called open sentences.
In statement:
4y + 8 = 6y + 3
variable is y
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
Solve the following equation.
-4y + 8 = 4 (2y - 2) -2 (-16 + 8y)
A. y= -4
B. y= 4
C. y= -2
D. y= -6
- 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
- 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
