One Step
2x = 10
x = 5
x = 4
4(a+2) = 16
a = 2
5x = 2x + 6
x = 2
What is the inverse of addition?
Subtraction
x - 4 = 12
x = 16
5x + 6 = 26
x = 4
3(b+1) = 21
b = 6
3x - 14 = 10x
x = -2
What is the inverse of multiplication?
Division
7 + y = 15
y = 8
2x - 1 = 9
x = 5
2(4 - c) = 20
c = -6
5x + 4 = 7x - 16
x = 10
What is the inverse of division?
Multiplication
5a = 15
a = 3
4b - 12 = -8
b = 1
-5(10-e) = -40
e = 2
6x - 12 = -3x + 6
x = 2
What is the inverse of subtraction?
Addition
x/3 = 2
x = 6
15 - 4d = 23
d = -2
-3(f - 3 - 5) = 24
f = 0
5 - 8x = 3x + 11
x = -2
Square root.
