Solve the system using elimination 4x-7y=3
x-7y=-15

x=6 and y=3

Step-by-step explanation:

4x - 7y = 3 (1)

x - 7y = -15 (2)

equation(1) - equation (2)

3x = 18

Divide bothside by 3

x = 18/3

x= 6

also, multiply equation (2) by 4

4x - 28y = -60(3)

subtract equation(3) from equation(1)

21y = 63

divide bothside by 21

y = 63/21

y = 3

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20
