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

you can use a^2+ b^2=c^2

x > 4

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.

if it's asking for the proper expression then it could be 8x= .8 each person would get a .1   portion of the turkey
