Question

please help me

Answer 1

what kind of equation is
X-4=5 ?

Answer 2

a line

Answer 3

:-O

Answer 4

is it conditional , identity or contradiction

Answer 5

x=# is a condition

Answer 6

10 = 25 is a contradiction

Answer 7

10 = 10 is an identity, all real number solution

Answer 8

contradiction
AN EQUATION THAT HAS NO ANSWERS (NULL SET or NO SOLUTION
3(x+2)=3x-5
3x+6=3x-5
Subtract (3x) from both sides
6=-5
False Statement
No Solution


conditional equation
AN EQUATION THAT IS TRUE BASED "ON THE CONDITION" THAT THE SOLUTION IS X=(A CERTAIN) THAT MAKES THE EQUATION TRUE
3(x+2)=2x-5
3x+6=2x-5
Subtract 3x from both sides AND Subtract 6 from both sides
x=-11
The equation is true based on the condition that x=-11


identity

AN EQUATION THAT HAS ALL REAL NUMBERS AS ITS ANSWERS. At some step in the solving of the equation you will get the same IDENTICAL terms on both sides of the equation.
3(x+2)=3x+6
3x+6=3x+6(Note the same terms on both sides)
COULD STOP HERE and say the solution is ALL REAL NUMBERS
If you Subtract 3x from both sides AND Subtract 6 from both sides you will get
0=0
