Answer:
4(2x-3)=8x-12 is identity
3x +5=3x-7 is impossible
Explanation:
A conditional equation is an equation that is true for some values and false for others
an identity equation is an equation that is true no matter what value you plug in
an impossible equation is an equation that has no solutions.
lets first try to solve
4(2x-3)=8x-12
distributive property, distribute the 4
8x-12=8x-12
this is an identity!
now for the second equation
3x+5=3x-7
add 7 to both sides
3x+12=3x
subtract 3x from both sides
12=0
wait a minute. This equation is false. this means it has no solutions. its an impossible equation.
