Answer:
x=-7
Step-by-step explanation:
9x + 16 = 4x - 19
Subtract 4x from each side
9x-4x + 16 = 4x-4x - 19
5x+16 = -19
Subtract 16 from each side
5x+16 -16 = -19-16
5x = -35
Divide each side by 5
5x/5 = -35/5
x = -7
in order to solve this , make x the subject of formula:
9x + 16 - 4x = -16
5x = -19 - 16
5x =-35
x = -35 / 5
