Question

Solve the equation for 11

Answer 1

z = 5

Explanation:

We are given the following equation and we are supposed to solve it:

2 (3z - 2) + 8 = 34

According to the order of operations to solve an expression, we will start by solving the brackets first:

6z - 4 + 8 = 34

Keeping variable at one side and taking all the constants at the other side of the equation to get:

6z = 34 - 8 + 4

6z = 30

z = 30/6

z = 5

Answer 2

Option D is correct.

Value of z =5

Explanation:

Given the equation:
`2(3z-2)+8=34`

Using distributive property:
`a\cdot (b+c) = a\cdot b+ a\cdot c`

Apply distributive property in the given equation we have;

`6z - 4 + 8 = 34`

⇒
`6z +4 =34`

Subtract 4 from both sides we get;

6z + 4 -4 = 34-4

Simplify:

6z = 30

Divide by 6 to both sides of an equation, we get;

z = 5

Therefore, the value of z is, 5
