Is x+1/2=x-1/2 true?

Sedaia [141]

$\frac{x+1}{2}=\frac{x-1}{2}$ is not true

Step-by-step explanation:

We need to find if $\frac{x+1}{2}=\frac{x-1}{2}$ is true?

Solving:

$\frac{x+1}{2}=\frac{x-1}{2}$

Cross Multiplying

$2(x+1)=2(x-1)$

$2x+2=2x-2$

$2x-2x=-2-2$

$0=-4$

Since both sides of the equation are not equal, so there is no solution.

So, $\frac{x+1}{2}=\frac{x-1}{2}$ is not true.

4x + 3y = 5<br> 2x – y=5<br> Use substitution method

lukranit [14]

Answer: Slope = -2.667/2.000 = -1.333

x-intercept = 5/4 = 1.25000

y-intercept = 5/3 = 1.66667

Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
