29. because If you add 15 and 14 you will get that answer
Answer:
-37/5= y
x=11/5
Step-by-step explanation:
4x-3y=31
-3y=-4x+31 regroup it to match the other
-2 y=(2x-3)(-2) multiply by -2 to get -4x
-3y=-4x+31
-2y=-4x+6 adding
-5y=37 divide
4x-3(-37/5)=31
subtract 22 on both sides
hope this helps :)
