n = 5 9 n − ( 3 + n ) = x x = 9 ⋅ 5 − ( 3 + 5 ) x = 45 − 8 x = 37 X i s e q u a l 37.
9*5=45 (3+5)=8 45-8= 37 x=37
By substituting n = 5 into the equation 9 n − ( 3 + n ) = x , we calculate x = 37 . This is found by first calculating 9 ( 5 ) = 45 and 3 + 5 = 8 , and then performing the subtraction. Therefore, the answer is x = 37 .
