Lis collects 86 buttons then she gives some to Matt now lia has 61 buttons. how many buttons dose lia give Matt?

25 buttons

Step-by-step explanation:

Lia as 86 buttons

Matt has unknown number of buttons

Lia gives Matt unknown number (g) of buttons

Lia now has 61 buttons

Let n represent the number of buttons Lia gave= ???

Let b represent the buttons Lia originally collected= 86

Let g represent how much Lia has now= 61

1. Plug numbers in and make the algebraic expression

In algebraic form...

b-g will = n = b-g=n

b is 86

86

g is 61

86-61

So let us do this subtraction

2. Subtract

86-61

6-1=5

8-6=2

Multiply 2 by 10 because it is in the tens place

(2*10)+5

20+5

25+61=86

So

Lia had 86 buttons

She gave away ???

Now she has 61

How much did she give away...

25 buttons!
