Question

x + x + x =30
y+y+x=20
2z+2z+y=13
x+y2zx×1z=?
​

Answer 1

3x = 30 so, x=10

2y + x = 20 so y = 5

4z + y = 13 so, z=2

x + (y)square zx ×z = 10 + 25×2×10×2

=10 + 1000 =1010

Answer 2

3x=30

x=10

y+y+X=20

2y+10=20

2y=10

y=5

2z+2z+y=13

4z+5=13

4z=13-5

4z=8

Z= 2

x+y2zx ×1z=10+5×2×2×10×1×2=410 Ans
