Question

X + y = 40
x + 10 = 60

What is the value of x? Of y?

Answer 1

x = 50

y = -10

Explanation:

x + y = 40

x + 10 = 60

60 - 10 =x

60 - 10 = 50

x = 50

50 + y = 40

40 - 50 = y

40 - 50 = -10

y = -10

Answer 2

Hey!

------------------------------------------------

Solve for x:

x + y = 40

x + y - y = 40 - y

x = 40 - y

50 - 10 = 40

50 + (-10) = 40

x = 50

y = -10

------------------------------------------------

Solve for x:

x + 10 = 60

x + 10 - 10 = 60 - 10

x = 50

------------------------------------------------

Hope This Helped! Good Luck!
