Question

solve for z.
3z - 10 = z + 10 + 4z
z =
submit

Explanation:

Step1: Combine like terms on right

$3z - 10 = 5z + 10$

Step2: Subtract $3z$ from both sides

$-10 = 2z + 10$

Step3: Subtract 10 from both sides

$-20 = 2z$

Step4: Divide by 2 to solve for z

$z = \frac{-20}{2}$

Answer:

$z = -10$
