If 1/(x+3)=2 , find the value of
1/(x+5).

1

Step-by-step explanation:

1/(x+3) = 2

2(x+3) = 1

2x+6=1

2x=1-6

2x=-5

x=-5/2

1/(x+5) = 1/ (-5/2+5)

= 1/((-5+10)/5)

= 1/(5/5)

= 1/1

= 1

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?
