3x - y = 2
y = 2x - 9
Substitute:
3x - 2x - 9 = 2
x - 9 = 2
x = 11
Substitute your answer into any equation:
y = 2x - 9
y = 2(11) - 9
y = 22 - 9
y = 13
Answer:
x = 11 ; y = 13

Their fraction is calculated as thus
Hello! For this question, we are looking for the percent of change. The formula for percent of change is change/original = x/100, where change is tge difference between two numbers, and the original is the previous number. 136,500 - 130,000 is 6,500. The original number is 130,000. It would be set up like this:
6,500/130,000 = x/100
Let's cross multiply the values. 6,500 * 100 is 650,000. 130,000 * x is 130,000x. That makes 650,000 = 130,000x. Now, divide each side by 130,000 to isolate the x. 130,000x/130,000 cancels out. 650,000/130,000 is 5. There. x = 5% increase. The answer is A: 5%.
