2(3)+3(13)= 45 if j=3 and h=13 you need to plug those numbers in where the letters are
Sin 270 = -1, cos 270 = 0, tan 270 is undefined.
Since they are like terms, add -2x and -4x which gets you -6x
-7 - 6x = 17
Cancel out -7 and add 7 to 17
-6x = 24
24 / -6x = -4x
X = -4
The mystery number is 16 because 16 - 6 = 10.
