`3262=712+3x`

`2550=3x`

`x=850`

Answer 2

Explanation:

2.)

Let the number be x.

Thus,

2x-13=9

2x = 22

x = 11

3.)

2x-7= 15

2x = 22

x = 11

4.)

200 = 2x + 50

2x = 200 - 50

2x = 150

x = 75 Php

5.)

Cost of 2 blouses = 356 x 2 = 712Php

let the cost of the pants be x.

Thus,

3x + 712 = 3262 ( 3x because she bought 3 of them)

3x = 2550

x = 850Php

Hope this helps! :)
