your number was 12.

let x be the number:

(x * 2) + 50 = 74

To solve for x, we need to reverse what was done to get the answer of 74.

Since 50 was added to arrive at 74, we deduct 50 from 74.

74 - 50 = 24

We then divide 24 by 2 to get the original number.

24/2 = 12.

Your number was 12.

To check:
(12 * 2) + 50 = 74
 24 + 50 = 74
74 = 74

74 - 50 = 24
24 / 2 = 12 
12 * 2 + 50 = 74

Solve |2x - 5| = 4 I dont know what you solve for
ICE Princess25 [194]

Hello!

Answer:

\huge\boxed{x = 1/2, 9/2}

|2x - 5| = 4

Solve for the negative and positive expressions:

2x - 5 = 4

2x = 9

x = 9/2

------------

-(2x - 5) = 4

-2x + 5 = 4

-2x = -1

x = 1/2.

Therefore, the solutions are x = 1/2 and 9/2.

Trevor solved the system of equations below. What mistake did he make in his work?
wariber [46]

2x + y = 5

x − 2y = 10

y = 5 − 2x

x − 2(5 − 2x) = 10

x − 10 + 4x = 10

5x − 10 = 10

<em>add 10 to each side</em>

<em>5x-10+10 = 10 + 10</em>

<em>5x=20</em>

5x = 0    <em>this is the error</em>

He needs to add 10 to each side
