Step-by-step explanation:

If a+b=50

When b=30

a=50-b

a= 50 - 30

a=20

Therefore 20(a)+30(b)=50

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
