3. Find x.<br> 8x - 37<br> 5x + 17<br><br><br> I really need help with this
sveticcg [70]

Answer: here is your steps Simplifying

8x + -37 = 5x + 17

Reorder the terms:

-37 + 8x = 5x + 17

Reorder the terms:

-37 + 8x = 17 + 5x

Solving

-37 + 8x = 17 + 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.

-37 + 8x + -5x = 17 + 5x + -5x

Combine like terms: 8x + -5x = 3x

-37 + 3x = 17 + 5x + -5x

Combine like terms: 5x + -5x = 0

-37 + 3x = 17 + 0

-37 + 3x = 17

Add '37' to each side of the equation.

-37 + 37 + 3x = 17 + 37

Combine like terms: -37 + 37 = 0

0 + 3x = 17 + 37

3x = 17 + 37

Combine like terms: 17 + 37 = 54

3x = 54

Divide each side by '3'.

x = 18

Simplifying

x = 18

Question 12 (5 points)
NemiM [27]

Answer:

D) If WX = XY and XY = YZ, then WX = YZ.

Step-by-step explanation:

The transitive property states that if a=b and b=c, then a=c. So, if two different values equal to the same, separate value, then they are also congruent. The answer choice, d, represents this idea because WX and YZ both equal XY and are shown to be equal.
