Question

If x equals 7. What is 3x-47

Answer 1

Answer: x = -26

Step-by-step explanation:

3x-47

substitute x with 7: 3(7)-47

3(7) = 21 -47 = -26

Answer 2

Answer:

-26

Step-by-step explanation:

x=7

3 is being multiplied by X

replace X with 7 in your equation

Your equation should then look like this: 3(7)-47

The parentheses around the 7 indicate that the 7 is being multiplied by the 3 or in other words: (3*7)-47

multiply 3 and seven before subtracting 47

3*7= 21

Once you have your answer to that subtract 47, your answer should be a negative # because you are subtracting a larger # from a smaller #

21-47= -26

so if X equals 7.  3x-47= -26
