Simplify each side of the equation.

6-4 = k-3k

simplifying is easy! we simply add or subtract like terms on each side.

6-4=2

1-3=-2 and then add k which is the variable so - 2k

The equation would be 2=-2k and then we can divide both sides by - 2 to isolate the variable to get - 1=k

k = - 1

Step-by-step explanation: 6-4 = k-3k

subtract: 2 = - 2k

divide both sides by - 2: k = - 1
