Question

The cost of two tables and three chairs is $705. If the table costs $40 more than the chair,find the cost of the table and the chair

Answer 1

Answer:

the cost of the table is $\ 165$

the cost of the chair is $\ 125$

Step-by-step explanation:

Let

x-----> the cost of the table

y----> the cost of the chair

we know that

$2x+3y=705$ -----> equation A

$x=y+40$ -----> equation B

substitute equation B in equation A

$2(y+40)+3y=705$

$2y+80+3y=705$

$5y=705-80$

$y=625/5$

$y=\ 125$

Find the value of x

$x=y+40$  ----> $x=125+40=\ 165$
