Question

Solve the following system by the substitution method. Check the solution.

Solve the following system by the substitution method. Check the solution. 3x + 4y = 33 X = y +4 Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. The system has a single solution. The solution set is { } (Simplify your answer. Type an ordered pair.) O B. There are infinitely many solutions. The solution set is {(x,y)|3x + 4y = 33). OC. The solution set is the empty set.

Answer 1

IN above question has a unique solution if we substitute of value X in first or substitute has value Y input first then we have the same answer (7,3) so solution set only (7,3)

we Rave 3x+4y=33 - X=Y+4 Pust value of x in een ☺ we get 3(444) + 4y= 33 34+12+ 44= 33 74+ 12 = 33 => 74= 21 => H=3 and x = 4+4 => [x=7 which implies the system hag a Unique Solution (7,3).
