Here is are two equations: 1/x+ 1/y = 5/6 and
1/x-1/y = 1/6
I am wanting to solve this sorta equations by Ms-991 calculator. How can I do it?

there will be 35 boys in each team. : )

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

f(x)=2/3x-8, which give g(x) the greatest value.
