Resuelvo la situación realizando todas las operaciones a mano La finca de don Aldemar tiene una forma de rectángulo con medidas de 20 metros de largo y 15 metros de ancho, don Aldemar le ha hecho 45 surcos a lo largo, si quiere sembrar arveja necesita dos libras y media por surco. Para que le produzca cada surco 90 libras. - es en enteros

f(x) = y

f(-3) = -5

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: you need the equation in the question so i can answer it
