So the first thing to do is to simplify both sides of this equation:
<span>12.46x+4.5</span>=162
Next we shall subtract 4.5 from both sides so:
<span>12.46x+4.5−4.5</span>=<span>162−4.5</span>12.46x=<span>157.5
</span>Now that we are done with all those steps now here is the final steps so now we shall divide both sides by 12.46:
<span><span><span>12.46x/</span>12.46 </span>= <span>157.5/<span><span>12.46
</span>Ok so your final answer shall be:
</span></span></span>x=<span>12.640449
</span>I hope this helps you greatly!

Step-by-step explanation:
Absolute value of a number gives the positive quantity of the number.
For instance,
From this example, therefore we know that

In this question,
The number is -2
-2 + 4 = 2
2 is 2 less than 4
Answer:
a = 1/2 (1 ±sqrt(47))
Step-by-step explanation:
a^2-a+12=0
We will complete the square
Subtract 12 from each side
a^2-a+12-12=0-12
a^2-a=-12
The coefficient of a = -1
-Divide by 2 and then square it
(-1/2) ^2 = 1/4
Add it to each side
a^2 -a +1/4=-12 +1/4
(a-1/2)^2 = -11 3/4
(a-1/2)^2= -47/4
Take the square root of each side
sqrt((a-1/2)^2) =sqrt(-47/4)
a-1/2 = ±i sqrt(1/4) sqrt(47)
a-1/2= ±i/2 sqrt(47)
Add 1/2 to each side
a-1/2+1/2 = 1/2± i/2 sqrt(47)
a = 1/2± i/2 sqrt(47)
a = 1/2 (1 ±sqrt(47))
