if : a <span>≡ 5 ( mod 7) ....(1)
b </span><span>≡ 6 ( mod 7) ...(2)
(1)×(2) : ab </span><span>≡ 30 ( mod 7)
</span>but : 30 = 7×4 + 2 ..... so : 30 ≡ 2 ( mod 7)
then : ab ≡ 2 ( mod 7)
Answer:

Step-by-step explanation:

Split the second term (5x) into two terms. Multiply the coefficient of the first term (2) by the constant term (3):

Find which two numbers add up to 5 and multiply into 6:

Split 5x as the sum of 3x and 2x:

Now factor out a common term for the first 2 terms:

And do the same for the last 2 terms:

Re-insert:

Factor out the common term 2x+3 and insert the values in front of the parentheses (x and 1):

Separate the parentheses and equal them to 0. Solve for x:

and

Answer: 63.63
