Let the algebraic adventure begin!
1.
What replaces 'y' in the equation 3y = 21?
6
7
8
9
Solving for 'y' you divide both sides by 3. Hence, y = 7.
2.
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.
3.
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.
4.
Simplify the expression 4a + 2a.
6a
8a
2a
4a
When you add the like terms, 4a + 2a, it gives you 6a.
5.
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.
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.
Simplify the expression 4x + 3x - 2x.
9x
5x
6x
7x
4x + 3x gives 7x and then subtracting 2x gives 5x.
9.
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.
10.
Simplify the expression 3x + 2x?
6x
5x
x
x2
With the like terms 3x and 2x, when you add them up it gives 5x.
