Then only the first option is in a linear expression format
9x-2
6 times 20 equals 120 and equals 26 when added together
Answer:
6
Step-by-step explanation:
But not too sure tho make sure of it
Im gonna assume you mean 6 - (1/3)x = -1. Your notation is not super clear. If so, solution is as follows:
6 - (1/3)x = -1 [subtract 6 from both sides]
-(1/3)x = -7 [multiply both sides by -3]
x = 21
