A+2=e b-2=e c×2=e d:2=e divide 45 in 4 parts example (20,15,3,7) equation will be correct as abcd
Answers
b-2=e
2c=e
d/2=e
dunno wat last part is but since they all equal e
a+2=b-2=2c=d/2
I am guessing that a+b+c+d=45 such that a+2=b-2=2c=d/2
interesting
make in terms of one thing
let's do a
a+2=b-2
a+4=b
a+2=2c
(a+2)/2=c
a+2=d/2
2(a+2)=d
sub
a+(a+4)+[(a+2)/2]+(2(a+2))=45
distribute some
a+a+4+(a+2)/2+2a+4=45
add like terms
4a+8+(a+2)/2=45
minus 8
4a+(a+2)/2=37
mult both sides by 2
8a+a+2=74
add like terms
9a+2=74
minus 2
9a=72
divide 9
a=8
sub back
a+4=b, 8+4=b=12
(a+2)/2=c, (8+2)/2=10/2=c=5
2(a+2)=d, 2(8+2)=2(10)=d=20
a=8
b=12
c=5
d=20

Area = √p(p −a )(p −b )(p −c )
where p is half of perimeter of the triangle and a,b,c are the side lengths.
p = (25 + 25 + 48) / 2
p = 49
Area = √49(49−25)(49−25)(49−48)
Area = 168

3x-2y=9
y=2x-7
Answers
3x-2(2x-7)=9
3x-4x+14=9
-1x=-5
x=5
next solve for y
y=2x-7
y=2(5)-7
y=10-7
y=3
And now we have x=5, and y=3.
3x - 2y = 9
3x - [2(2x-7)]= 9
3x - (4x - 14) = 9
3x - 4x + 14 = 9
-x + 14 = 9
-x = -5
x = 5
y = 2x - 7
y = 2(5) - 7
y = 10 - 7
y = 3
