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

Step-by-step explanation:
u not the only one
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
