First what you wanna do is get y by it’s self. To do that is to first add 5 on each side.
-5+3y=-4
+5 +5
3y= 1
Than you divide 3 on each side and it would give you y=1/3 if it’s a fractions problem but if you looking for decimals you would have to divide 1 by 3 which gets you .33333333.
Step-by-step explanation:
x = the number
2x - 25 = x
2x = x + 25
x = 25
1/2 of 40= 20
40/5=8
20+8=28
