Step by Step Equations Solving

2x - 3 + 4x = 27

• x= 12
• x = 4
• x = 5
• x = 15

Which choice describes the step needed to isolate the variable? (Tap outside of the gray box to see the equation.)

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.

Solve the equation:
20.)  5 = 4 - x

• x= 1
• x = -1
• x = 2
• x = -24.5

7(1 - y) = -3(y - 2)

• x = 1/4
• x = 4
• x = 5

Translate: 
Four times a number plus six IS 30.

• 4 + 6 = 30
• 4x + 6 = 30
• x + 4 times 6 = 30
• 30 = 4x
