Question

Solve for x:
-6 + 4x = 13

Answer 1

x=4.75

explanation: you would subtract -6 since there is an invisible adding sign and then you would subtract -6 from both sides so you would do 13- -6 and that would give you 19. so then it would be 4x=19 and you would divide by 4 since you are doing inverse operation so 19 divided by 4 is 4.75

Answer 2

x = 19/4

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Explanation:

Step 1: Define equation

-6 + 4x = 13

Step 2: Solve for x

1. Add 6 to both sides: 4x = 19
2. Divide both sides by 4: x = 19/4

Step 3: Check

Plug in x to verify it's a solution.

1. Substitute: -6 + 4(19/4) = 13
2. Multiply: -6 + 19 = 13
3. Add: 13 = 13

Here, we see that 13 does indeed equal 13.

∴ x = 19/4 is a solution of the equation.
