Step-by-step explanation:
Hey there!
Here, The equations are:
y = x+1........(i)
4x + y = 6........(ii).
Now,
Putting equation (i) in (ii)
4x + y = 6
4x + (x + 1) = 6
5x + 1 = 6
5x = 6-1
Therefore, x= 1
Putting the value of x in equation (i).
y = x+1
y = 1+1
Therefore the value of y is 2.
<u>Check</u><u>:</u>
y = x+1
2 = 1+1
2=2 ( True ).

Answer:
Use simultaneous equation for this problem
y= number of adults
x = number of children
3y + 2x = 160
y + x = 60
then we double the second equation
3y + 2x = 160
2y + 2x = 120
we cancel x by elimination
3y - 2y = 160 - 120
y = 40
Step-by-step explanation:
