3(7) = 21 -47 = -26
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
