Question

Please solve, I already know how to do the equation! Please show an easy way to solve solution, thx!

Answer 1

One bed costs $25 and one toy costs $10

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
