50-6x=y
since each car wash is 6 dollars and you do not know the number of cars washed it is 6x
50-6x is because you need to find out how much is left in the card so you subtract the total from how much she spent
It is X=2 you have to see where it touched line
Hello,
To this question, It's only directly sum the equations:
y + y = 7x - 7x +7+19
2y = 0x + 26
2y = 26
y = 26 ÷ 2
y = 13
Now only to replace y = 13 in the equation of up or of down.
Then stay:
y = 7x + 7
13 = 7x + 7
7x = 13 -7
7x = 6
x = 6 / 7
