Are x+4=5 and 2x+8=10 equivalent equations?

Yes

Step-by-step explanation:

You can find the answer to this question by finding the value of x in both equations.

Let's start off with the first equation:

To find the value of x, you're going to have to subtract 4 from both sides. This is because you're looking for the value of only x, not x + 4. To leave x alone, you'd have to subtract 4, leaving that side with just x.

The answer to the first equation is x = 1.

Now let's start on the second equation:

Like before, you're looking for x alone and in this equation, 8 is being added to 2x. Although x itself isn't alone, you'll first start off with 2x since you can simplify it thrughout the process. In this equation, you're going to subtract 8 from both sides to leave the variable x alone.

Now you're left with 2x = 2. Since you're looking for the value of x alone, you're going to divide both sides by 2. Because x is being multiplied by 2(2 times x = 2x) you're going to divide(opposite of multiply), which will cancel out the 2(in 2x).

The answer to the second equation is x = 1.

Since both equations have the same solution, the answer to your question would be yes.

Hello There!

Yes

If you want to know if your two equations are equivalent, let's try finding the answer to both of them.

Let's find x.

We all know addition and subtraction. So let's just do

So 5-4 is equal to 1.

So the answer for this equation is

Let's move on to your second equation.

Now we must subtract 8 from both sides.

And this equals

Let's divide the both sides by 2.

The fraction is gonna equal one.

So

Now you have your answer for the second equation. Both answers were the same.

So the answer to your question is YES.

a - base

b - exponent

so,

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
