Solve for x
4x = 24
x=6
f(x) = x + 3
y = x - 3
or
f(x) = x - 3
3x = 2y + 5
x = (2y + 5) / 3
Division
Multiplication
x+5 = 17
x=12
y = 4x
y = x/4
5+x = y
x = y - 5
Addition
Subtraction
x - 5 = 17
x = 23
f(x) = 5x + 4
(y-4)/5
2y + 3x = 5
A Positive
x/6 = 3
(x divided by 6 equals 3)
x = 18
y = 5(x+4)
y = (x/5) - 4
or
y = x - 20
x = (4 - 3y) / 2
subtraction of a negative
addition of a negative
or
Subtraction of a positive
24/x = 4
(24 divided by x equals 4)
x = 6
y = (x-4) / 4
y = 4x + 4
2x + 3y = 5x - 2y
x = (5y) / 3
