Will mark brainliest! find the solution of this system of equations. 2x+6y=4 8x-5y=45

x= -1, y= 1

Step-by-step explanation:

2x + 6y = 4(1)

8x - 5y = 45(2)

multiply equation (1) by 4

8x + 24y = 16(3)

subtract equation (3) by (2)

29y = 29

y = 1

then substitute y=1 in equation (1)

2x + 6(1) = 4

solving for x

x = -2/2 = -1

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
