6 = a + a + 4
36 = y  5y  12
16 = 2(x  1)  x
8  3(x  4) = 4
how do you do all of these?? explain as many as you can

how do you do all of these?? explain as many as you can

6=a+a+4, combine the a's
6=2a+4, subtract 4 from each side
64=2a+44
10=2a, divide both sides by two and you get a
a=10/2=5
36=y5y12, add twelve to both sides
36+12=y5y12+12, combine the y's
48=4y, divide both sides by 4 and you get y
y=48/4=12
16=2(x1)x, use the distributive property for the 2(x1)
16=2x2x, combine the x's and add two to both sides
16+2=(2xx)2+2, simplify everything and you get x
18=x
83(x4)=4, use the distributive property for the 3(x4)
83x4*3=4, simplify, do 4*3=12
83x12=4, subtract 812
(812)3x=4
43x=4, add 4 to both sides
3x=8, divide both sides by 3
x=8/3, approximately 2.67
