Solve for y in terms of x: 3x - 4y = 10

• y = -3x + 10

• y = 0.75x + 2.5

• y = -3/4x + 10

• y = 3/4x - 2.5

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.
  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.
