Answer:

a=-2

Step-by-step explanation:

4a-14=7a-8

Subtract 7a from both sides:

4a-14-7a=7a-8-7a

Group like terms:

4a-7a-14=7a-8-7a

Simplify the arithmetic:

-3a-14=7a-8-7a

Group like terms:

-3a-14=7a=-7a-7a-8

Simplify the arithmetic:

-3a-14=-8

Add 14 to both sides:

-3a-14+14=-8+14

Simplify the arithmetic:

-3a=-8+14

Simplify the arithmetic:

-3a=6

Divide both sides by-3:

Cancel out the negatives:

Simplify the fraction:

Simplify the signs:

Find the greatest common factor of the numerator and denominator:

Continued fraction:

[3; 1, 99]

Possible closed forms:

399/100 = 3.99

log(54)≈3.988984

8/(3 π) + π≈3.9904190

1/2 (e! + 1 + e)≈3.989551

-(sqrt(3) - 3) π≈3.983379

(14 π)/11≈3.9983906

25/(2 π)≈3.978873

(81 π)/64≈3.976078

(2 e^2)/(1 + e)≈3.974446

(π π! + 2 + π + π^2)/(3 π)≈3.988765

2 π - log(4) - 3 log(π) + 2 tan^(-1)(π)≈3.987955

2 - 1/(3 π) + (2 π)/3≈3.988291
