Question

Is x=-4 a solution to the equation —3z + 10 = 5?

Answer 1

For the given equation, there is no variable x but z is a variable in the linear equation. Since x is not a variable of the equation, we can't put the value given.

But if we plug the value of -4 in place of z:

➝ -3(-4) + 10

➝ 12 + 10

➝ 22 which is not equals to 5.

Hence, this equation is not satisfying for the value of variable given that is 4. Thus, -4 is not a solution to the given equation

Answer 2

No.

Explanation:

First, note that there is no variable x inside the equation. Therefore, there is nothing for the -4 to plug into.

However, if you meant to put the same variable, it still will not work.

Plugging in -4 for z (if you meant z = -4), would give you the following:

Assuming that z = -4

-3(-4) + 10 = 5

-12 + 10 = 5

-2 ≠ 5.

Therefore, even if you did mean to put the same variable, it will still not be correct.
