3𝑋+21−5𝑋=−9

Equation Solution

3X + 21 - 5X = -9

Step 1: Combine like terms on the left side:

3X - 5X + 21 = -9

Simplify the X terms:

-2X + 21 = -9

Step 2: Subtract 21 from both sides:

-2X + 21 - 21 = -9 - 21

This simplifies to:

-2X = -30

Step 3: Divide both sides by -2:

X = -30 / -2

Simplify the fraction:

X = 15

The solution to the equation is X = 15.

5X-4X+24=24

Steps to Solve the Equation

Step 1: Combine Like Terms

Combine like terms to simplify the equation:

5x - 4x + 24 = 24

x + 24 = 24

Step 2: Move Constant Term

Move the constant term \(24\) to the other side of the equation by subtracting:

x + 24 - 24 = 24 - 24

x = 0

Step 3: Final Solution

So, the solution to the equation is x = 0.

9X+4X-2=63

9X + 4X - 2 = 63

Step 1: Combine like terms on the left side:

9X + 4X - 2 = 63

Simplify the X terms:

13X - 2 = 63

Step 2: Add 2 to both sides:

13X - 2 + 2 = 63 + 2

This simplifies to:

13X = 65

Step 3: Divide both sides by 13:

X = 65 / 13

Simplify the fraction:

X = 5

The solution to the equation is X = 5.

7X+4X-17=49

Equation Solution

Solving the Equation

7X + 4X - 17 = 49

Step 1: Combine like terms on the left side:

7X + 4X - 17 = 49

Simplify the X terms:

11X - 17 = 49

Step 2: Add 17 to both sides:

11X - 17 + 17 = 49 + 17

This simplifies to:

11X = 66

Step 3: Divide both sides by 11:

X = 66 / 11

Simplify the fraction:

X = 6

The solution to the equation is X = 6.
