Answer:
Step-by-step explanation:
-------------------------- (1)
-------------------------- (2)
Multiply Eq. (1) by 13 and (2) by 9
<u>Equation (1):</u>
--------------------(3)
<u>Equation (2):</u>
------------------------(4)
Subtract Eq. (2) from (1)
39x - 36x = -264
3x = -264
Dividing both sides by 3
x = -88
<u>Put x = -88 in Eq. (1)</u>
3(-88)+9y³ = -21
-264 + 9y³ = -21
9y³ = -21 + 264
9y³ = 243
Dividing both sides by 9
y³ = 27
Taking cube root on both sides
y = 3
Ordered Pair = (x,y) = (-88,3)
Hope this helped!
