Is 2(x+3)=5x+6-3x always true or never true?

egoroff_w [7]

Answer:

always true

Step-by-step explanation:

Distribute the left side

2(x + 3) = 2x + 6

Simplify the right side

5x + 6 - 3x ← collect like terms

= 2x + 6

Thus

left side = right side , so always true

Solve for n: 1/4 (n-2)=1/4n-1/2

alisha [4.7K]

Answer:

See below:

Step-by-step explanation:

So, we start off with the equation: $\frac{1}{4} (n-2) = \frac{1}{4}n-\frac{1}{2}$

If we simplify, we can use the distrubutive property to simplify the equation:

Here is how it goes:

$\frac{1}{4} (n-2) = (\frac{1}{4} * n )+(\frac{1}{4}*-2)$

So upon simplification of that, we get here: $\frac{1}{4}n + -\frac{1}{2}= \frac{1}{4}n-\frac{1}{2}$

Hm, somethings off, do you see that they are the same thing...

So, that means that there would be infinately many solutions.

You can plugin any number and you would get the same result!

Q.13 is no solution since the y intercept of the 2 equation differ but gradient is the same therefore if you were to draw a graph there wont be any intersection between the equations
