Answer:
The bench costs 450
Step-by-step explanation:
Let t = cost of the table
b = cost of bench
t+b = 846
t = b-54
t+b =846
Substituting t = b-54 into the above equation
b-54 +b =846
Combine like terms
2b -54 = 846
Add 54 to each side
2b-54+54 = 846 +54
2b =900
Divide by 2
2b/2 = 900/2
b =450
The bench costs 450
