Simplify the expression. (–5 – c)(–1) a.5 + c b.–5 + c c.5 – c d.–5 – c

(-5-c)(-1) =

multiply -5 x -1 = 5

multiply -1 x -c = c

 so you get 5+c

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
