Answer:
x = 5.7 years after 2000
Step-by-step explanation:
So the year when both the amount of users were the same can be found by using the both equations to solve for x (since y is the same)
48x + y = 729
we will take the value of y from this equation and use it in the other equation
y = 729 - 48x
135x - 2y = -140
135x - 2(729 - 48x) = -140
135x -1458 + 98x = -140
231x = 1318
x = 1318/231
x = 5.7 years after 2000
Easy
plug them in
0.33=1/4(x)
times both sides by 4/1 (4/1 times 1/4=4/4=1)
0.33*4/1=4/4x
1.32=1x
1.32=x
x=1.32
