Can sombody please help me with this math problem?
Molodets [167]

y=2/3y-3


1. y = 2/3 (9)-3   multiply 9 and 2 =18/3

 y=18/3-3 divide 18 and 3 =6

y=6-3 subt. 3

y=3



2.  -11=2/3x - 3

 -11+3 = 2/3 x   add 3 to both sides to cancel -3

 -8=2/3 x  

(3/2)-8 = (2/3)3/2 x multiply both sides by reciprical of 2/3

-24/2 = x  divide

-12=x

10x + 10y = −10<br> 9x + 10y = −18
andreev551 [17]

Answer:

Step-by-step explanation:

10x+10y=-10

9x+10y=18

= 10x+10y=-10

-9x-10y=18

= x=8

step two is to find y:

10x+10y=-10

10(8)+10y=-10

80+10y=-10

10y=-90

y=-9

your answer:

(x,y)= (8,-9)
