Which expression is equivalent to 14-9?
a) -14=9
b)-9-14
c)9-14
d)14+(-9)

14+(-9)

Step-by-step explanation:

14 - 9 = 5

-14=9 (Wrong). -14 is not equal to 9.

-9-14 = -23(Wrong). -23 is different from 5.

9-14 = -5(Wrong). Negative 5 is different from positive 5.

14+(-9) = 14-9= 5(Correct). The answer 5 is correct.

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
