1 .

Simplify the expression 4a + 2a.

6a

8a

2a

4a

When you add the like terms, 4a + 2a, it gives you 6a.

2 .

Simplify the expression 3x + 2x?

6x

5x

x

x^{2}

With the like terms 3x and 2x, when you add them up it gives 5x.

3 .

What is the simplified form of the expression 4y + 5 - 2y?

2y + 5

10y

2y - 5

6y + 5

Combine like terms. 4y - 2y = 2y. Therefore 2y + 5 is the simplified form.

4 .

What is the solution for the equation 4x + 2 = 14?

1

2

3

4

First subtract 2 from both sides to get 4x = 12, then dividing by 4 gives you x = 3.

5 .

Simplify the expression 4x + 3x - 2x.

9x

5x

6x

7x

4x + 3x gives 7x and then subtracting 2x gives 5x.

6 .

If x = 5 and y = 3, what is the value of the expression 2x - y?

5

6

7

8

Substitute x with 5 and y with 3 in the expression. Hence, 2x - y = 10 - 3 = 7.

7 .

What is the value of 'x' in the equation 2x = 16?

4

8

6

2

If 2x equals 16, then dividing both sides by 2 gives you x = 8.

8 .

What replaces 'y' in the equation 3y = 21?

6

7

8

9

Solving for 'y' you divide both sides by 3. Hence, y = 7.

9 .

What is the solution of the equation 8x - 3 = 13?

1

2

3

4

Add 3 from both sides first to get 8x = 16, then divide by 8 to get x = 2.

10 .

What is the solution of the equation 6x + 2 = 14?

1

2

3

4

Subtract 2 from both sides to get 6x = 12. Dividing by 6 gives x = 2.
