Remember that to solve an equation we need to isolate the variable in one side. To do it we can perform any mathematical operations we want as long as we perform the operations to both sides of the equation.
Let's solve our equation step by step
Step 1. Subtract
from both sides of the equation



Step 2. Subtract 3 from both sides of the equation


Step 3. Divide both sides of the equation by 




We can conclude that the next step is: subtract 3 from both sides of the equation.
Well if you use graph paper you can graph the points you already have and then you can find the slope of the line easiest that way, the next point would be. (-1,8)
Answer:
75 × 12 + 30m = 990
∴ m = 3
Step-by-step explanation:
Assume the number of months Talia brings a guest to be 'm'.
So the amount of Talia has to pay for guests for one year is $ 30m .
So, <em>total amount of money Talia has pay for one year = (monthly membership cost)×(number of months in a year) + (additional amount for guests)</em>
Total cost = $990
Monthly membership cost = $75
Number of months in a year = 12
Additional amount for guests = $ 30m
∴ The equation which gives you the number of moths she brought guests is:
990 = 75×12 + 30m
990 = 900 + 30m
990-900 = 30m
30m = 90
∴ m = 3
