Answer: 15 = x

Step-by-step explanation: Don't be thrown off if your variable <em>x</em> appears on the right side of the equation. Just solve for <em>x</em> in the usual way by first isolating the <em>x</em> term which in this case is 4x.

Since 14 is being added to 4x we start by

subtracting 14 from both sides of the equation.

On the left, 82 - 14 is 68 and on the right, 14 - 14 cancels out.

So we have 68 = 4x.

To get <em>x</em> by itself since 4 is being multiplied by <em>x</em>,

divide both sides of the equation by 4.

On the left, 68 divided by 4 is 15 and

on the right, the 4's cancel.

So 15 = x.

Answer:

17

Step-by-step explanation:

82=4x+14

If you subtract 14 from both sides:

4x=68

Divide both sides by 4:

x=17

Hope this helps!

Prove identity : (2 cos 2x)/(cot x – tan x) = sin 2x​
Nimfa-mama [501]

Step-by-step explanation:

(2 cos(2x)) / (cot x – tan x)

Multiply top and bottom by sin x cos x:

(2 cos(2x) sin x cos x) / (cos² x – sin² x)

Use double angle formula:

(2 cos(2x) sin x cos x) / (cos(2x))

2 sin x cos x

Use double angle formula:

sin(2x)

What is 2y+5x-z=4y+6x and im solving for y
kap26 [50]
Simplifying
2y + 5x + -1z = 4y + 6x

Reorder the terms:
5x + 2y + -1z = 4y + 6x

Reorder the terms:
5x + 2y + -1z = 6x + 4y

Solving
5x + 2y + -1z = 6x + 4y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.
5x + 2y + -6x + -1z = 6x + -6x + 4y

Reorder the terms:
5x + -6x + 2y + -1z = 6x + -6x + 4y

Combine like terms: 5x + -6x = -1x
-1x + 2y + -1z = 6x + -6x + 4y

Combine like terms: 6x + -6x = 0
-1x + 2y + -1z = 0 + 4y
-1x + 2y + -1z = 4y

Add '-2y' to each side of the equation.
-1x + 2y + -2y + -1z = 4y + -2y

Combine like terms: 2y + -2y = 0
-1x + 0 + -1z = 4y + -2y
-1x + -1z = 4y + -2y

Combine like terms: 4y + -2y = 2y
-1x + -1z = 2y

Add 'z' to each side of the equation.
-1x + -1z + z = 2y + z

Combine like terms: -1z + z = 0
-1x + 0 = 2y + z
-1x = 2y + z

Divide each side by '-1'.
x = -2y + -1z

Simplifying
x = -2y + -1z
