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

the cost of the table is

the cost of the chair is

Step-by-step explanation:

Let

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

y----> the cost of the chair

we know that

-----> equation A

-----> equation B

substitute equation B in equation A

Find the value of x

 ---->

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
