We can solve this by following the steps I'm about to explain.

1) Write the equation out.

• 4x + 1 = 2x - 3

2) Get the numbers and variables to their own side.

• 4x + 1 = 2x - 3

• 4x + 1 - 1 = 2x - 3 - 1

• 4x = 2x - 4

• 4x - 2x = 2x - 2x - 4

• 2x = -4

3) Perform the opposite operation that is holding the variable together. (2x = 2(x) so we're multiplying - we need to divide)

• 2x = -4

• 2x/2 = -4/2

• x = -2

4) Check your solution

• 4x + 1 = 2x - 3

Substitute the value of X for every x in the equation.

• 4(-2) + 1 = 2(-2) - 3

• -8 + 1 = -4 - 3

• -7 = -7
