(1 - 2) j

Subtract the numbers

- j

- j - 3 j - 4 = 0

Subtract the terms

More Steps

Simplify

- j - 3 j

Collect like terms by calculating the sum or difference of their coefficients

(- 1 - 3) j

Subtract the numbers

- 4 j

- 4 j - 4 = 0

Move the constant to the right-hand side and change its sign

- 4 j = 0 + 4

Removing 0 doesn't change the value,so remove it from the expression

- 4 j = 4

Change the signs on both sides of the equation

4 j = - 4

Divide both sides

\frac{4 j}{4} = \frac{- 4}{4}

Divide the numbers

j = \frac{- 4}{4}

Solution
