Answer 2

$\bold{ANSWER≈}$

12+x / 4 = 4

12+x / 4 .4 = 4.4

12+ x = 16

X = 4

x={4}

PREMISES

(4+3+x+5)/4=4

ASSUMPTIONS

Let “average”=the “mean”, commonly thought of as the average in the mathematical sense.

CALCULATIONS

(4+3+x+5)/4=4

(12+x)/4=4

4(12+x)/4=4(4) (Multiply both sides of the equation by 4 in order to express all terms as whole numbers)

12+x=16

(12–12)+x=16–12

0+x=16–12

x=16–12

x=

4

PROOF

If x=4, then the equations

(4+3+x+5)/4=4

(4+3+4+5)/4=4

16/4=4 and

4=4 prove the root (zero) x=4 of the expression (4+3+x+5)/4=4
