Choose a system of equations with the same solution as the following system: 4x − 2y = 6
2x + y = 5

A) −4x − 2y = 10
2x − 3y = 21

B) 4x + 2y = 10
10x + y = 21

C) −4x − 5y = −1
2x − 6y = 10

D) 3x + 2y = 6
9x + y = 17

the answer is C

whats the question?

step-by-step explanation:

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
