Literal Equations Part 1

Solve for y.

8x + 4y= 16

• y = -8x + 16

• y = 2x -4

• y = -2x + 4

• y = -8x + 12

Solve for y.

5x - y = 16

• -y = 5x + 16

• y = 5x + 16

• x = 5y - 16

• y = 5x - 16

7x + 3 = 10 
Solve for x

• x = 13/7
• x = 91
• x = 1
• x = 49

Solve for y.

5x - y = 16

• -y = 5x + 16

• y = 5x + 16

• x = 5y - 16

• y = 5x - 16

Solve y - x = 5 for y.

• y = 5 + x

• y = -5 - x

• y = -5 + x

• y = 5 - x

Solve -2 = 4x + y for y.

• y = -2 + 4x

• y = 2 - 4x

• y = -2 - 4x

• y = 2 + 4x

What should we do first to solve for x?
y=mx+b

• Add
• Subtract
