4y=-20+3x and 4y=13.6x-20
so
-20+3x=13.6x-20
3x=13.6x
3=13.6 so it is wrong and system doesn’t have solution
Answer:
Step-by-step explanation:
An unknown number minus 8.
Answer:
5, -⅓
Step-by-step explanation:
x = 2:
4x + 3y = 23
3y = 23 - 4(2)
3y = 15
y = 5
x = 6:
4x + 3y = 23
3y = 23 - 4(6)
3y = -1
y = -⅓
Answer:
Step-by-step explanation:
no. of sides n=5
sum of interior angles=(n-2)×180=(5-2)×180=3×180=540
72+2x+99+89+3x=540
5x+ 260=540
5x=540-260
5x=280
x=56°
