Question

What is 5z/3 - 4 = 1?

Answer 1

z=3

Explanation:

multiply both sides of the equation by 3.

5z/3-4=1

3(5z/3-4)=3x1 (3x1 is just 3)

3(5z/3-4) =3

3x5z/3-3x4=3

(cancel out any denominators that are the same, so 3.)

it leaves you with:

5z-3x4=3 (multiply 3x4)

5x-12=3

move the constant (-12) to the right side of the equation.

-12 becomes +12 since you are switching sides.

5z=3+12

5z=15

divide 5 by both sides.

5z/5=15/5

it leaves you with z=3

Answer 2

Answer: z = 3

Explanation:

In order to solve this equation, we should isolate z.

Given equation:

`\sf{\cfrac{5z}{3}-4=1}`

Add 4 to both sides:

`\sf{\cfrac{5z}{3}=5}`

Multiply both sides by 3:

`\sf{5z=15}`

Divide both sides by 5:

`\sf{z=3}`

Therefore, z = 3.
