In two or more complete sentences, describe how the substitution method works for solving a two-order system of equations.

The first step is to set one of the equation equal to x or y. Then substitute this value into the other equation to find the value of the other variable. Finally, put the value obtained into the relation taken at the start.

Step-by-step explanation:

Let us consider an example,

3x + y = 8

x + y = 6.

The first step is to set one of the equation equal to x or y.

i.e. x = 6 - y.

Next step is to substitute this value into the other equation.

i.e. 3×(6-y) + y = 8

i.e. 18 - 3y + y = 8

i.e. -2y = -10

i.e. y = 5.

Finally, we put this value of y into the relation taken at the start

i.e. x = 6 - y

i.e. x = 6 - 10

i.e x = 4.

Hence, the solution of this system of equations using substitution method is (x, y) = ( 4, 5).

if x = 1, then the answer is 3.5

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
