Answer:

Jumper, y = 172

Shirt, x = - 105

Step-by-step explanation:

Let :

Shirt = x

Jumper = y

5x + 4y = 163 - - (1)

3x + 2y = 29 - - - (2)

Multiply (1) by 3 and (2) by 5

15x + 12y = 489 - - - (3)

15x + 10y = 145 - - - (4)

Subtract :

12y - 10y = 489 - 145

2y = 344

y = 344 / 2

y = 172

Put y = 172 in (3)

15x + 12(172) = 489

15x + 2064 = 489

15x = 489 - 2064

15x = - 1575

x = - 105

The values ;

Jumper, y = 172

Shirt, x = - 105

We weren't supposed to obtain a negative value, kindly check if the parameters given are correct.

Question 1 - You need to split the L shape into  2 shapes.

6mm x 2mm = 12mm

and

5mm x 2mm = 10mm

add 12mm and 10mm 
the area is 22mm squared (a little 2 above the mm)

question 2 - you need to do the same

4mm x 2mm = 8mm squared 
7mm x 2mm = 14mm squared
area - 22mm squared
