Answer:
k = -4
Step-by-step explanation:
Step 1: Subtract 1 from both sides
Step 2: Multiply both sides by 2
Step 3; Divide both sides by 5
[tex]\frac{5}{2}k+1=-9\\\\\frac{5}{2}k =-9-1\\\\\frac{5}{2}k = - 10\\\\5k = -10*2\\\\5k = -20\\\\k =\frac{-20}{5}\\\\k = -4[/tex]
Answer:
k= -4
Step-by-step explanation:
Solve for k by simplifying both sides of the equation, then isolating the variable.
Hope it helps!
