Question

3х +7=16
What’s the answer rn!!!

Answer 1

3х +7=16

move +7 to the other side

sign changes from +7 to -7

3x+7-7= 16-7

3x=9

divide both sides by 3 to get x by itself

3x/3= 9/3

x= 3

Answer: x= 3

Answer 2

x = 3

Explanation:

Isolate the variable, x. Note the equal sign, what you do to one side you do to the other. Do the opposite of PEMDAS.

First, subtract 7 from both sides:

3x + 7 (-7) = 16 (-7)

3x = 16 - 7

3x = 9

Isolate the variable x. Divide 3 from both sides:

(3x)/3 = (9)/3

x = 9/3

x = 3

x = 3 is your answer.
