Question

Re write the statement 19 +7 / 2 x 6 + 1 by including two pairs of brackets to make the total value equal to 2

Answer 1

y=2

PREMISES

y=the expression 19+7/2×6+1 rewritten by including two sets of brackets or parentheses to get a result of 2

CALCULATIONS

To clearly express the mathematical phrase 19+7/2×6+1 to get a result of 2 requires specific parenthetical treatment.

y=19+7/2×6+1 becomes

y=(19+7)/(2×6+1)

y=26/(12+1)

y=26/13

y=

2

PROOF

If y=2, then the inverse of the phrase (19+7)/(2×6+1) returns

y(2×6+1)=19+7

2(2×6+1)=19+7

2(12+1)=19+7

2(13)=26 and

26=26 proves the solution y=2 to the phrase (19+7)/(2×6+1)
