The sum of Jahiem and his sister's age is 21. If Jahiem is 7 years older than his sister, write and solve a system of equations using ) to represent Jahiem's age and s
to represent his sister's age

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)
