Answer:
yes it is true that a linear system of three equations with two variables is inconsistent because when we solve the equations variables can be obtained by only first two equations which are considered first. and third equation is useless.
use p e m d a s
Step-by-step explanation:
p=parenthesis
e=exponents
m=multipltly
d=divide
a=add
s=subtract
x = -7
4x - 9 = 7x + 12
~Add 9 to both sides
4x = 7x + 21
~Subtract 7x to both sides
-3x = 21
~Divide -3 to both sides
Best of Luck!
