Answer:
Number 5 is ' 2(x) + 1 = y '
I dont know how to solve number 6.
Step-by-step explanation:
you take your x variables and compare them to each other and compare them to the y variables. each x variable goes into the y variable 2 times. thats where the 2(x) comes from. then once yiu do that for all your x variables, you must look to see what they have in common. in this case all of them are one digit less than the y value. so you add that to your equation and it become ' 2(x) + 1 = y '

Answer: 3 (c)
Step-by-step explanation:
2 * 3 = 6 therefore 15 * 3 = 45$
3 * 2 = 6 therefore 21 * 2 = 42$
5=4x+2x-7
5+7=6x
12=6x
12/6=6x/6
2=x
