x + y = 46
x is six more than four times the value of y
so replace x with that
6+4y + y = 46
add
4y+y=5y
so
6+5y=46
subtract 6 from both sides to remove the 6 in the left.
5y = 40
Divide both sides by 5, the coefficient of y. 5y/5=y and 40/5=8

Therefore
(4y+6) +y = 46
We can combine the like terms:
5y + 6 = 46
Subtract 6 on both sides:
5y+6-6=46-6
Therefore 5y =40
Divide by 5 on both sides
5y/5 = 40/5
Therefore
y= 8
We found y but to find the value x we use y.
X= 4y+6
Therefore
x= (4*8)+ 6
Therefore
x= 32 + 6
x= 38.
