¿Qué pasa cuando tenemos dos números iguales con el signo = dentro del proceso de resolver un sistema?
Ejemplo 0=0
8=8
Hay inifinitas soluciones.
No hay solución.
Posible error en el proceso utilizado.
Resuelve por sustitución
y = -1x - 5
4x - 8y = 4
(-3, -2)
(5, -7)
(3, 9)
(-5, 4)
Resuelve por sustitución
y = 7x + 7
2y + 2x = -18
(5, 0)
(9, 18)
(-2, -5)
(1, 16)
S=3F−24 Solve for F
F= 3S+8
F= 3S+24
F= 3S+24
F= 3(S+24)
Solve for y
5x - y = 16
-y = 5x + 16
y = 5x + 16
x = 5y - 16
y = 5x - 16
Solving the formula P = 2L + 2W for W
2 answers
W=2P−2L
W=2P−L
W=2P+ 2L
W=2P+2L
5x - y = 16
pV = nRT
solve for R
R= p/n + V/T
R= pV - nT
R= (pV-n)/T
R=pV/nT
What is the best method to use?
−4x − 2y = −12
4x + 8y = −24
Graphing because the answer is a point
Substitution because a variable is defined
Elimination because the equations are in standard form and all the variables have a number
What is the best method to use?
y = −3x + 5
5x − 4y = −3
Graphing because the answer is a point
Substitution because a variable is defined
Elimination because the equations are in standard form and all the variables have a number
