(State Step to Solve & Solution)
a + 3 = -8
Add -3 to Both Sides or Subtract 3 from Both Sides
a= -11
a - 5 = 4
Add 5 to both sides
a=9
Simplify
5x + 4x
9x
5a = 25
Divide both sides by 5
a=5
a/9 = 9
Multiply both sides by 9
a=81
x + 8 = 12
Add -8 or Subtract 8 from both sides of the equation
x=4
a - 10 = 13
Add 10 to both sides
a=23
Simplify
5 + 4x - 3x - 6
x - 1
25n = 625
25
a/7 = 4
Multiply both sides by 7
a=28
a + (-66)= -21
Add 66 to both sides of the equation
a=45
a - 56 = 8
Add 56 to both sides
a=64
Simplify
-(6x + 8)
-6x - 8
-18g = 486
Divide both sides by -18
g=-27
a/-10 = 4
Multiply both sides by -10
a=-40
a + (-30) = 120
Add 30 to Both Sides
a =150
a - 15 = -15
Add 15 to both sides
a=0
Simplify
-5(3x - 9)
-15x + 45
12y = -144
-12
a/12 = -4
Multiply both sides by 12
a=-48
a + (-12) = -86
Add 12 to both sides
a= -98
a - 48= -76
Add 48 to both sides
a=-28
Simplify
8 - 9(3x - 9) + 26x
-x + 89
-8x = -56
Divide both sides by -8
x=7
b/-12 = -7
Multiply both sides by -12
b=84
