y = (x + 4)/x
x = xy -4 solve for y
x = 6
2x + 7 = x + 3 + 10
x = 3/2y + 3
2x - 3y = 6 solve for x
y = 2/3 x - 2
2x - 3y = 6 solve for y
x = 12
3(x - 1) = 2x + 9
x = 2/3y + 2
3x - 2y = 6 Solve for x
y = 3/2x - 3
3x - 2y = 6 solve for y
Rational
-67.98
x = 7/2 - y
7 = 2(x + y) solve for x
Natural

1/3
x = 5
10+5x=7x
Integer
100, -68, 2, -56,
x = -6
12 - 5 - (3 + x) = -2 - 2x
x = -3
4x + 2x + 2 = 3x - 7
x = -4
4x + 2x - 5 = 7x - 1
x = 10
4x - 6 = -7x + 4 + 10x
x = 3
5x-16=14-5x

x = ½y + 8
y = 2(x - 8) solve for x
x = -1
−18 − 6x = 6 (1 + 3x)
