Answer:
One bed costs $25 and one toy costs $10
Step-by-step explanation:
Let's rewrite the first equation so that "b" is isolated...
55 = b + 3t
Subtract 3t from both sides
b=55-3t
Now we can solve using substitution (substitute 55-3t for b)
125 = 3(55-3t)+5t
Distribute the 3
125 = 165-9t+5t
Combine like terms
125 = 165-4t
Subtract 165 from both sides
-40=-4t
Divide both sides by -4
t=10
Now, plug 10 back into the first equation to solve for x...
55 = b+3(10)
55 = b+30
Subtract 30 from both sides
b=25
One bed costs $25 and one toy cost $10
