Question

2/5z-7=3 heeeeeeeeeelp

Answer 1

2/5z - 7 = 3
2/5z = 3 + 7
0,4z = 10
z= 10 ÷ 0,4
z= 25

Answer 2

2/5z=3+7 2/5z=10 z=10:2/5 z=25

Answer 3

I'd be happy to help you solve the equation. Let's solve for "z" in the equation:

2/5z - 7 = 3

First, let's isolate the term with "z" on one side of the equation. Start by adding 7 to both sides:

2/5z - 7 + 7 = 3 + 7

This simplifies to:

2/5z = 10

Now, to solve for "z," you can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2. This will cancel out the fraction on the left side:

(2/5z) * (5/2) = 10 * (5/2)

On the left side:

(2/5z) * (5/2) simplifies to (2/5z) * (5/2) = z

On the right side:

10 * (5/2) simplifies to 25

So, you have:

z = 25

Therefore, the solution to the equation is:

z = 25
