x=0.27

Step-by-step explanation:

We are given the equation;

The first step is to add 4.2 on both sides of the equation;

The next step will be to divide both sides of the equation by 1.2;

Next we take natural logs on both sides of the equation;

Finally, we divide both sides by 4*ln10 and simplify to determine x;

i got 142 as my answer

step-by-step explanation:

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
