(−2−2)k
Subtract the numbers
−4k
−4k−58
−4k−58=0
Move the constant to the right-hand side and change its sign
−4k=0+58
Removing 0 doesn't change the value,so remove it from the expression
−4k=58
Change the signs on both sides of the equation
4k=−58
Divide both sides
44k=4−58
Divide the numbers
k=4−58
