7a-4=3a+27+4a
7a-4=7a+27
you sure you type the right question?
15/y+11-10/y+3=0
15/y-10/y=5/y 11+3=14
5/y+14=0
o-14=-14
5/y=-14
y=-5/14
D when dividing u subtract exponents
I'm pretty sure y is 47 and x is 46... hope that helps!
-8=-(x+4)
remember the invisible 1
-8=-1(x+4)
distribute using distributeiv porpety
a(b+c)=ab+ac
-1(x+4)=-x-4
-8=-x-4
add 4 to both sides
-4=-x
mutily both sides by -1
4=x
