match the equivalent expressions.
12 − 3y − 2x + x + 2x
3x + 2y − 2x + y + 12
x + 3y + 2x − 3x + 7 + 5
3y + 12
x − 3y + 12
5 + 2y + 7x − 4x + 3y − 17
4y + 3y + 3x − 6y − 10 − 2
3x + y − 12
x + 3y + 12

One pair of equivalent expressions is:

x - 3y + 12

12 - 3y - 2x + x + 2x

Second,

x + 3y + 12

3x + 2y - 2x + y + 12

third,

3y + 12

x + 3y + 2x - 3x + 7 + 5

four,

3x + y - 12

4y + 3y + 3x - 6y - 10 - 2

Step-by-step explanation: The most important step to do is to simplify the equations down. We do this by finding common variables.

Common Variables are pairs such as 12x and 32x, and not 12x and 32y or 12 and 32.

9. cannot be simplified any further.

Now, we start to match the equations.

Equation 1 is the same as Equation 5

Equation 2 is the same as Equation 9

Equation 3 is the same as Equation 4

Equation 6 is the same as none of them.

Equation 7 is the same as Equation 8.

And there you are have it!

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

y -5 = (-1/4)(x + 8)
