Answer:
x = 6
y = 7
a = 1/4
Step-by-step explanation:
Equation 1:
2(3x+2) = 2x + 28
6x + 4 = 2x + 28
4x = 24
Equation 2:
5y+13 = -43-3y
8y = -56
y = -7
Equation 3:
8a + 8 = 16 - 24a
32a = 8
first equation=6
second equation=15
Third equation=
2(3x+2)=2x+28
6x+4=2x+28
collect like terms
6x-2x=28-4
4x=24
Divide both sides by 4
4x/4=24/4
x=6
second equation
5y+13=43-3y
5y-3y=43-13
2y=30
Divide both sides by 2
2y/2=30/2
y=15
Third equation
4(2a+2)=8(2-3a)
8a+8=16-24a
8a+24a=16-8
32a=8
Divide both sides by 32
32a/32=8/32
a=1/4
John gets 24 dollars
Divide 40 into 5 because 2+3 equals 5.
Each "section" equals 8. Now, multiply that by 3(John's section)
You get 24.
