ok please answer this math questions!! :)
solve each equation or formula for the variable specified.
1. 3x - 4y =7, for x
2. a(y + 1) = b, for y
3. ex - 2y = 3z, for x
4. 3/5y + a = b, for y
y = mx + b,for m

3x = 4y+7
x= (4y-7)/3
ay+a = b
ay = b-a
y= (b-a)/a
ex-2y = 3z
ex =3z +2y
x = (3z+2y)/e
3/5y +a = b
3/5y = b-a
Y= (5/3)(b-a)
y=mx+b
y-b= mx
(y-b)/x = m

1. x = 4/3y + 7
2 . y = b\a - 1
3. x = 3/e(z) + 2/e(y)
4. y = 5/3b - 5/3a
m = y/x - b/x
Those are the answers I can give you b/c no other info is being used
