the third option
because 1/3 is not equal to three
where as if we replace the x with one in all the other we would find that the equation is correct.
Answer:
a=2
b=3
c=5
d=-3
Step-by-step explanation:
a + b = c
a-c=d
a+b=5
a+b =5
a = 2
2+b =5
Subtract 2 from each side
2+b-2 =5-2
b=3
a + b = c
2+3 = c
5=c
a-c=d
2-5 =d
-3 =d
2 solutions, the root to the equation is the same as the root to the solution also known as “double roots”
