Answer:

<h2>3(x-2)+x=4x+6</h2>

Step-by-step explanation:

The first equation is the one that doesn't have solution. Let's demonstrate this:

3(x-2)+x=4x+6\\3x-6+x=4x+6\\4x-6=4x+6\\4x-4x=6+6\\0=12

<em>As you can observe, the equation doesn't have any solutions, because it result in a false statement.</em>

<em></em>

If we solve the other equations, we would have:

3(x-2)+x=2x-6\\3x-6+x=2x-6\\4x-6=2x-6\\4x-2x=-6+6\\2x=0\\x=0

3(x-2)+x=3x-3\\3x-6+x=3x-3\\4x-3x=-3+6\\x=3

3(x-2)+x=4x-6\\3x-6+x=4x-6\\4x-6=4x+6\\6=6

The last equation has infinite solutions.

Therefore, the only one that doesn't have any solutions is

<h3>3(x-2)+x=4x+6</h3>

Answer:

3(x-2)+x=4x+6

Step-by-step explanation:

case 1) we have

3(x-2)+x=4x-6

Solve for x

3x-6+x=4x-6

4x-6=4x-6

0=0 ----> is true for any value of x

therefore

The equation has infinite solutions

case 2) we have

3(x-2)+x=2x-6

3x-6+x=2x-6

4x-2x=-6+6

2x=0

x=0

case 3) we have

3(x-2)+x=3x-3

3x-6+x=3x-3

4x-3x=-3+6

x=3

case 4) we have

3(x-2)+x=4x+6

3x-6+x=4x+6

4x-4x=6+6

0=12 ------> is not true

therefore

The equation has no solution

Evaluate each expression if r= −3, s=4, and t= −7.
saul85 [17]

Answer:

a. 5

b. -1

c. 132

Step-by-step explanation:

Given:

r =-3, s = 4 and r = -7

\sqrt{s} +|r| \\ \sqrt{4} +|-3| \\ 2 +3 \\ 5

\frac{s -r}{t} \\ \frac{4 -(-3)}{-7} \\ \frac{4 +3}{-7} \\ \frac{7}{-7} \\ -1

2s^3 +r -t \\ 2(4)^3 +(-3) -(-7) \\ 2(64) -3 +7 \\ 128 -3 +7 \\ 132
