Answer:
He buys 8 desks and 6 chairs can i have branliest
Step-by-step explanation:
Set up a system of equations
desks = y chairs = x
x+y=14
125x + 515y = 4870
Eliminate,
-125x -125y = -1750
125x + 515 y = 4870
390 y = 3120
y = 8
substitute in 8
x + 8 = 14
x = 6
Let number of chairs be x and number of desks be y
Total number of chairs and desks = 14
x + y = 14 --------------(i)
Total cost = $ 4870
125x + 515y = 4870 ------------(ii)
Multiply equation (i) by (-125).
(i)*(-125) -125x - 125y = -1750
(ii) <u>125x +515y = 4870</u> {Now add}
390y = 3120
y = 3120/390
Plug in value of y in equation 1
x = 14 - 8
Number of chairs = 6
Number of desks = 8

use desmos it's a graphing calculator just put in the equation
Answer: i cant graph but polt 0,4 on the y axis the go up 1 to the right 8
