X + 5 = -9 X + 5 - 5 = -9 -5 X = -14 -6 + X = -4 -6 + 6 + X = -4 + 6 X=2

Try the following on your paper.
10 = X + 3 5+X=9 6=3+X

X=7 X=4 X=3

Equations with subtraction
X-5=8 X - 5 + 5 = 8+5 X = 13 5-X=6 5-5+X=6-5 X=1

Try the following on your paper.
X - 7 = -1 X - 4 = 66 8=X-2 -8 = X - 2

X=6 X = 70 X = 10 X = -6

Multiplication of Equations
3X = -9 3X/3 = -9/3 X = -3 -5X = -40 -5X/-5 = -40/-5 X=8

Try these on your paper.
4X = -16 -1X = 9 6 = 5X 12X = 3

X = -4 X = -9 X = 6/5 X = 1/4

Division of Equations
1/2X = 4 (2/1)1/2X = 4(2) X=8 -3/4X = 6 (-4/3)(-3/4)X = 6(-4/3) X = -8

Try these on your paper.
