Question

Can somebody solve 3(3z−10)= −3

Answer 1

First, distribute the 3:
9z - 30 = -3

Next, isolate the variable by adding 30 to both sides:
9z = 27

Finally, divide both sides by 9 to solve for z:
z = 3

So, the solution to the equation is z = 3.

Answer 2

Answer: x = 3

Big Idea:

In order to solve the equation for z, we should isolate the variable.

Explanation:

Given equation:

`\bf{3(3z-10)=-3}`

I am going to begin by using the distributive property:

`\bf{3*3z-3*10=-3}`

`\bf{9z-30=-3}`

Add 30 to both sides.

`\bf{9z=-3+30}`

`\bf{9z=27}`

`\bf{x=3}` {answer}
