Step 2: Divide by 3

Answer explanation

Step 1: Subtract 6 from both sides

Step 2: Divide both sides by 8

Step 3: Since the multiplier is negative, we must reverse the direction of the inequality sign.

-2(x+2) < 14

• x < - 5
• x > -5
• x < -9
• x > -9

Solve:

-8b - 8 > 56

• b > 6

• b < -8

• b > -8

• b > 7/2

Solve for y: 
3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Solve for y:
2x + 2y = 6

• y = - x + 3
• y = x + 3
• y = 2x +6
• y = - 2x + 6

Solve for y: 
4x + 3y = 9

• y = -3/4x + 3
• y = -4x + 9
• y = -4/3x + 3
• 3y = -4x + 9
