Question

What is the value of x in the equation 3x - 13 = 10?

a) x = 23
b) x = 7
c) x = 6
d) x = 5

Answer 1

To solve for x in the equation 3x - 13 = 10, add 13 to both sides and then divide by 3. The correct value of x is 7, matching option b.

Step-by-step explanation:

To find the value of x in the equation 3x - 13 = 10, we need to isolate x. First, add 13 to both sides of the equation to cancel out the -13 on the left side:

3x - 13 + 13 = 10 + 13

3x = 23

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

3x / 3 = 23 / 3

x = 7.67

Therefore, the correct value of x is 7, which corresponds to option b.
