Solving Linear Equations

Solving Equations Using the Subtraction and Addition Properties of Equality

Solve:
x + 11 = -3
m - 4 = -5
n - (3/8) = (1/2)
a - 3.7 = 4.3
3x - 7 - 2x - 4 = 1
3(n - 4) - 2n = -3

Solving Equations Using the Division and Multiplication Properties of Equality

Solve:
4x = -28
a/(-7) = -42
-r = 2
(2/3)x = 18

Solving Equations with Variables and Constants on Both Sides

Solve:
3.4x + 4 = 1.6x - 5
3(x + 2) = 18
-(x + 5) = 7
4(x - 2) + 5 = -3
8 - 2(3y + 5) = 0
(1/2)(6x - 2) = 5 - x
3(x - 2) - 5 = 4(2x + 1) + 5
0.24(100x + 5) = 0.4(30x + 15)

Solving Equations with Fraction or Decimal Coefficients

Solve:
1 = (1/2)(4x + 2)
0.8x - 5 = 7
0.06x + 0.02 = 0.25x - 1.5
0.25x + 0.05(x + 3) = 2.85
