Question

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Match each equation to the value of a that makes the equation true.

Answer 1

`\LARGE{ \underline{ \blue{ \rm{Required \: answer:}}}}`

What to do?

We have to solve the equations and find the out the value of a in each case. Accordingly we have to drag the value of the equation.

1) 2a + 3(a + 1) = 8

⇒ 2a + 3a + 3 = 8

⇒ 5a + 3 = 8

⇒ 5a = 5

⇒ a = 5/5 = 1

Drag the tile with number 1 on the top.

2) 3a - 2a - 4 = 0

⇒ a - 4 = 0

⇒ a = 4

Drag the tile with number 4 on the top.

3) 6(2a - a + 1)= 24

⇒ 2a - a + 1 = 4

⇒ a + 1 = 4

⇒ a = 3

Drag the tile with number 3 on the top.

4) 4 + 3(a + 2) = 16

⇒ 3(a + 2) = 12

⇒ a + 2 = 12/3 = 4

⇒ a = 2

Drag the tile with number 2 on the top.

Answer 2

• 1, 4, 3, 2

Explanation:

• 2a + 3(a + 1) = 8
• 2a + 3a + 3 = 8
• 5a = 5
• a = 1

-----------------------

• 3a - 2a - 4 = 0
• a - 4 = 0
• a = 4

-----------------------

• 6(2a - a + 1) = 24
• 6(a + 1) = 24
• a + 1 = 4
• a = 3

-----------------------

• 4 + 3(a + 2) = 16
• 4 + 3a + 6 = 16
• 3a + 10 = 16
• 3a = 6
• a = 2
