Multiply both equations by a constant

(- , )

Step-by-step explanation:

9x + 8y = 3 → (1)

6x - 12y = - 11 → (2)

Multiplying (1) by 12 and (2) by 8 and adding will eliminate the y- term

108x + 96y = 36 → (3)

48x - 96y = - 88 → (4)

Add (3) and (4) term by term to eliminate y

156x = - 52 ( divide both sides by 156 )

x = = -

Substitute this value into either of the 2 equations and solve for y

Substituting into (1)

9(- ) + 8y = 3

- 3 + 8y = 3 ( add 3 to both sides )

8y = 6 ( divide both sides by 8 )

y = =

solution is (- , )

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
