1 answer:
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)
