Two Step Equations

How can you check if x = 4 is a solution to the equation 2x + 3 = 11?

• Substitute 4 into the equation: 2(4) + 3 = 8 + 3 = 11, which is true.

• Substitute 4 into the equation: 2(4) + 3 = 8 + 3 = 10, which is false.

• Check if 2(4) + 3 equals 12 instead of 11.

• Verify that 2(4) - 3 equals 5.

What is the solution to the equation 4(x - 1) = 28?

• x = 6

• x = 7

• x = 8

• x = 9

What is a two-step equation?

• A two-step equation is an algebraic equation that requires two operations to solve for the variable.

• A two-step equation is an equation that can be solved in one step.

• A two-step equation is a type of equation that has only one variable.

• A two-step equation is an equation that requires three operations to solve for the variable.

What is the solution to the equation 7x = 28?

• x = 2

• x = 3

• x = 4

• x = 5

How do you isolate a variable in a two-step equation?

• First undo multiplication or division, then undo addition or subtraction.

• Perform the same operation on both sides of the equation.

• Perform the inverse operations in reverse order: first undo addition or subtraction, then undo multiplication or division.

• Add or subtract the variable from both sides of the equation.

If 4x - 5 = 11, what is the first step to solve for x?

• Add 5 to both sides to get 4x = 16.

• Subtract 5 from both sides to get 4x = 6.

• Multiply both sides by 4 to get 16x - 20 = 44.

• Divide both sides by 4 to get x - 1.25 = 2.75.

What equation represents the situation: 'Shaun has four boxes. Each box has the same number of items. After removing 1 item from each box, he had 28 items left.'?

• 4(x - 1) = 28

• 4x - 4 = 28

• x/4 + 1 = 28

• 4x + 1 = 28

What is the first step to solve the equation 2x + 3 = 11?

• Subtract 3 from both sides to get 2x = 8.

• Add 3 to both sides to get 2x = 14.

• Multiply both sides by 2 to get 4x + 6 = 22.

• Divide both sides by 2 to get x + 1.5 = 5.5.

What is the solution to the equation 2x = 8?

• x = 2

• x = 4

• x = 6

• x = 8

What is the first step to solve the equation 7x + 35 = 63?

• Subtract 35 from both sides to get 7x = 28.

• Add 35 to both sides to get 7x = 98.

• Multiply both sides by 7 to get x + 5 = 9.

• Divide both sides by 7 to get x + 5 = 9.
