Question

The root of the equation 3x+7=22 is​

Answer 1

Answer:

Step-by-step explanation:

x = 5

Explanation:

Isolate the x term on the left side and move numbers to the right

subtract 7 from both sides : 3x + 7 - 7 = 22 - 7

now have : 3x = 15 , and dividing both sides by 3, will give value of x.

3 x 3 = 15 3 ⇒ x = 5

Answer 2

Step-by-step explanation:

Root of an equation is the value of x that satisfies the equation:

3x+7=22

⇒3x=15

⇒x=5
