Question

What value of x makes the equation below true? 7x+4=39

Option 1: 4
Option 2: 5
Option 3: 7
Option 4: 18

Answer 1

The value of x that makes the equation 7x + 4 = 39 true is 5. To find it, you subtract 4 from both sides of the equation and then divide by 7. the value of x that makes the equation true is 5, which corresponds to Option 2.

Step-by-step explanation:

To find the value of x that makes the equation 7x + 4 = 39 true, we need to solve the equation for x. Here is the step-by-step process:To find the value of x that makes the equation 7x + 4 = 39 true, we need to isolate x on one side of the equation. Here are the steps to solve the equation: 1. Begin with the given equation: 7x + 4 = 39 2. Subtract 4 from both sides of the equation to move the constant term to the right side. This is done to isolate the term with x on one side of the equation: 7x + 4 - 4 = 39 - 4 3. Simplify both sides of the equation: 7x = 35 4. Now we need to solve for x by dividing both sides of the equation by 7 to find the value of one x: 7x/7 = 35/7 5. Perform the division on both sides: x = 5 Thus, the value of x that makes the equation true is 5, which corresponds to option 2'.

1. Subtract 4 from both sides of the equation: 7x + 4 - 4 = 39 - 4, which simplifies to 7x = 35.
2. Divide both sides of the equation by 7: 7x / 7 = 35 / 7, which simplifies to x = 5.Therefore, the value of x that makes the equation true is 5, which corresponds to Option 2.
