Solve for x in the equation 3x + 7 = 22. What is the value of x?

• A. 4
• B. 5
• C. 6
• D. 7

Answer: (B)

To solve the equation \(3x + 7 = 22\), we start by isolating the variable \(x\). First, subtract \(7\) from both sides of the equation: \[ 3x + 7 - 7 = 22 - 7 \] This simplifies to: \[ 3x = 15 \] Next, to solve for \(x\), divide both sides by \(3\): \[ x = \frac{15}{3} \] This simplifies to: \[ x = 5 \] Thus, the value of \(x\) is \(5\). This is why the correct answer is the choice that states the value is \(5\).

To solve the equation (3x + 7 = 22), we start by isolating the variable (x). First, subtract (7) from both sides of the equation:

[

3x + 7 - 7 = 22 - 7

]

This simplifies to:

[

3x = 15

]

Next, to solve for (x), divide both sides by (3):

[

x = \frac{15}{3}

]

This simplifies to:

[

x = 5

]

Thus, the value of (x) is (5). This is why the correct answer is the choice that states the value is (5).
