Solving Equations

Solve the equation 5(3x+2) - 2(x - 3) = 23

• x = 7/13

• x = 3/5

• x = 9/13

• x = 5/13

Solve the equation:

• x = -23

• x = -27

• x = -29

• x = -11

Solve the equation: 4(x+3) = 27 + 4x

• x = 24

• No solution

• All real numbers

• x = -24

Solve the equation

• x = 82/11

• x = 85/11

• x = 81/11

• x = 76/11

Solve: 5-3x=2x+25

• x = -4

• x = -3

• x = -5

• x = 3

Solve: 4x + 9 = 13 - x

• x = 3/5

• x = 4/5

• x = 1/5

• x = 2/5

Write as an equation: "The sum of five and twice a number makes 11"

• 5(2x) = 11

• 5/2x = 11

• 5 + 2x + 11

• 5 + 2x = 11
