Answer 1

y + (30 + 3 +9:3) x 3 = 408

y + (33 +3) x 3 = 408

y + 36 x 3 = 408

y + 108 = 408

y=408-108

y=300

400 + (y + 4 + 16: 4) * 4 = 592

(y + 4 + 4) * 4 = 592-400

(y + 8) * 4 = 192

y+8=192:4

y+8=48

y=48-8

y=40

500 + (50 + y + 25:5) x 5 = 800

(50 + y + 5) x 5 = 800-500

(55 + y ) x 5 = 300

55 + y = 300:5

55 + y = 60

y=60-55

y=5

600 + (60 + 6 + y:6) x 6 = 1 038

(60 + 6 + y:6) x 6 = 1 038-600

(66 + y:6) x 6 = 438

66 + y:6 = 438:6

66 + y:6 = 73

y:6 = 73-66

y:6 = 7

y=7×6

y=42

Answer 2

y+(30+3+9:3)x3=408
y+(30+3+3)x3=408
y+36x3=408
y+108=408
y=408-108
y=300


400+(y+4+16:4)x4=592
400+(y+4+4)x4=592
400+(y+8)x4=592
400+4y+32=592
432+4y=592
4y=592-432
4y=160
y=160:4
y=40


500+(50+y+25:5)x5=800
500+(50+y+5)x5=800
500+(55+y)x5=800
500+275+5y=800
775+5y=800
5y=800-775
5y=25
y=25:5
y=5


600+(60+6+y:6)x6=1038
600+(66+1/6y)x6=1038
600+396+y=1038
996+y=1038
y=1038-996
y=42
