Answer:

x = 2

Step-by-step explanation:

To find the x-value that makes the equation true, we would have to solve for x in the equation. To do that, we would have to get the equation in the form x = _. That would be our answer.

4x - 3 = -9 + 7x

Add 9 to both sides to get rid of the -9 on the right side.

4x - 3 + 9 = 7x

Simplify.

4x + 6 = 7x

Subtract 4x from both sides to get rid of the 4x on the left side.

6 = 7x - 4x

Simplify.

6 = 3x

3x = 6

Divide both sides by 3 to get rid of the coefficient of 3 on the left side.

x = 6/3

Simplify.

x = 2

So, the x-value that makes the equation true would be 2.

I hope this helps. :)

The solution to the inequality |4x − 2| > 14 is x > 4 and x < -3

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Given the inequality:

|4x − 2| > 14

Hence:

4x - 2 > 14 or -(4x - 2) > 14

x > 4 or x < -3

The solution to the inequality |4x − 2| > 14 is x > 4 and x < -3

Answer:

15/16-3/4 is 3/16. (1/8 simplified)

Step-by-step explanation: Let the 4 turn into a 16. Multiply 4 by 4 to get 16. Then, multiply the numerator by the number you multiplied for the denominator. 3x4 is 12. Now, can subtract. 15-12=3.
