Question

Chris writes the expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .
Which of these are equivalent expressions? Select TWO correct answers.
A. x − 15
B. x − 3
C. x + 15
D. ( 12 x − 11 x ) + ( 3 − 18 )
E. ( 12 x − 11 x ) + ( 18 − 3 )
F. ( 12 x − 11 x ) + ( − 6 + 3 )

Answer 1

The equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) is

• x+15
• ( 12 x − 11 x ) + ( 18 − 3 )

The Correct option is (C) and (E)

What is Linear equation in one variable?

A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form ax+ b = 0.

The given equation is:− 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .

= -3x+18 + 12 x -8x-3

=x +15

The corresponding equation to the above equation is:

C. x+15

D. (12 x - 11x) + (3-18)

= x-15

E. (12 x - 11x) + (18-3)

= x+15

F. (12 x - 11x) + (-6+3)

= x-3

As from the above it can be seen that the equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) . is

• x+15
• ( 12 x − 11 x ) + ( 18 − 3 )
