Which is the correct algebraic expression after combining like terms? 6 c d + 3 c minus 7 d minus 3 c d + 4 d + one-third c 3 c d + 2 and two-thirds c minus 11 d 3 c d + 3 and one-thirds c minus 3 d 9 c d + 2 and two-thirds c minus 3 d 9 c d + 3 and one-thirds c minus 3 d

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

33/100 is what i got
