Solve this equation using the elimination method 4x+2y=6 ; 3x+2y=1

4

Step-by-step explanation:

Since they both contain 2y we can just subtract the second from the first to eliminate y

4x+2y-3x-2y=6-1

x=5, since 4x+2y=6 we have

4(5)+2y=6

20+2y=6

2y=-14

y=-7

So the solution point (x,y) is (5,-7)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
