What is the solution to the system of equations below? y=-1/3x+9 and y=2/3x-12

(21,2)
(21,-10)
(-21,16)
(-21,-26)

The correct answer option is (21, 2).

Step-by-step explanation:

We are given the following two equations and we are to find the solution to this system of equations:

--- (1)

--- (2)

Since the left hand side of the both the equation is equal so we can equate the right hand sides of these equations equal to each other.

x = 21

Substituting this value of x in (2) to find y:

y = 2

The correct answer is first option (21, 2)

Step-by-step explanation:

The given two equations are,

y=-1/3x+9 and y=2/3x-12

To find the solution

Two equations are

y=-1/3x+9    (1)

y=2/3x-12     (2)

(2) - (1) ⇒ 0 = 3/3x + (-12 - 9)

⇒0 = x - 21

x = 21

Substitute value of x in eq(1) we get,

y = -1/3 * 21 + 9 = -7 + 9 = 2

Therefore the solution is (21, 2)
