Jenny is solving the linear equation 12+3X-5=8x+8-5x. her final two steps are: 7+3x=3x+8
7=8

x has no solution.

Step-by-step explanation:

In a solvable linear equation, you will always be able to simplify to the point where you only have 1 x on either side of the equal sign.

If you can cancel the x's, then no value for x could ever work, even trial and error would eventually make you conclude that, as a constant, or a literal number, can never equal a different one unless they are the same; 7 will NEVER equal 8, in any circumstances.

So the linear equation has no solution.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

point m is on plane r
