Iknow i already asked this but this time it is 50 points
c=ax-bx
joseph claims that if a, b, and c are non-negative integers, then the equation has exactly one solution for x. select all cases that show joseph's claim is incorrect.

a. a-b=1,c=0
b. a=b, c≠0
c. a=b, c=0
d. a-b=1,c≠1
e. a≠b, c=0

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
