Question

Please answer properly.

Answer 1

Answer:

$1) y=-6$

$2)x=3$

$3) y=8$

$4)a=8$

Step-by-step explanation:

$4y+24=0$

subtract 24 from both sides

$4y=-24$

divide both sides by 4

$y=-6$

---------->>>>

$15+3=6x$

combine like terms

$18=6x$

divide both sides by 6

$3=x$

---------->>>>

$9y-72=0$

add 72 to both sides

$9y+72$

divide both sides by 9

$y=8$

---------->>>>

$8a=75-11$

combine like terms

$8a=64$

divide both sides by 8

$a=8$

Hope this is helpful.
