• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Solve for a:

-3a + 8 = 14

• a = -2

• a = -7.5

• a = 2

• a = 6

Solve the equation below:

• k = 152
• k = 176
• k = 5
• k = 27

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

solve for x

3x + 2(4x - 4) = 3

• 4

• 3

• 2

• 1

Solve the equation for y. 
2x + 3y = 4

• y = (4-2x)/3
• y = (2x-4)/3
• x  = (4-3y)/2
• y = (4-2x)/ -3

Solve the equation for w.  
^{x = w / a}

• w = a / x
• w = x / a
• w = ax
• x = wa

Solve for x. 
x + 7g = 9

• x = 9 - 7g
• x = 9 / 7g
• x = 9 + 7g
• x = 7g - 9
