Solve the equation:
3x - x + 4 = 4(2x +1)

x = 0

Step-by-step explanation:

Step 1: Write equation

3x - x + 4 = 4(2x + 1)

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

3(0) - 0 + 4 = 4(2(0) + 1)

4 = 4(1)

4 = 4

Step-by-step explanation:

3x - x + 4 = 4(2x +1)

2x + 4 = 8x + 4

2x - 8x = 4 - 4

-6x = 0

x = 0

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
