Solve the inequality -2z-3<5. what is the value of z?

agasfer [191]

Hey there!

The answer to your question is z > -4

We can solve this like it is an equation, with one exception. When you divide or multiply by a negative number, in an inequality, you have to flip the inequality sign.

-2z - 3 < 5 add 3 to both sides

-2z < 8 divide both sides by -2, and flip the inequality sign

z > -4

Good luck! Hope it helps, and have a great day!

What is the solution: 256x + 2 = 43x + 9

ruslelena [56]

Answer:

$x = \bf \frac{7}{213}$

Step-by-step explanation:

To find the solution to the equation, we have to rearrange the equation to make $x$ the subject:

$256x + 2 = 43x + 9$

⇒ $256x + 2 - 2 = 43x + 9 - 2$ [Subtracting 2 from both sides]

⇒ $256x = 43x + 7$

⇒ $256x - 43x = 43x + 7 - 43x$ [Subtracting $43x$ from each side]

⇒ $213x = 7$

⇒ $\frac{213}{213}x = \frac{7}{213}$ [Diving both sides by 213]

⇒ $x = \bf \frac{7}{213}$
