Answer:
x is 4
Step-by-step explanation:
Step one: Add 12x to both sides-
8x-19+12x=-12x+61+12x
20x-19=61
Step 2: add 19 to both sides
20x -19+19=61+19
20x=80
Step 3: divide both sides by 20
20x/20=80/20
x=4

Answer:
18 weeks
Step-by-step explanation:
In this question, we are asked to use an equation to show the number of weeks it took Hugo who received a certain amount in his birthday and continually saved a certain amount before he could gather a certain amount of money.
In this question, we understand that Hugo wants to buy a printer that costs $460. Fortunately, he had his birthday and he received $100 bucks. Now, let’s say the number of weeks he had to save for is w and he saves 20 per week. This means the total amount he hit from his savings would be 20w
Mathematically, we can use the equation below to model this scenario;
100 + 20(w) = 460
20w = 460 - 100
20w = 360
w = 360/20
w = 18 weeks
First if there are 47/80 we have to estimate like 47 is 50 and 82 is 80
