Answer 2

Answer:

6

Step-by-step explanation:

Solve equation [2] for the variable x

[2] x = -y + 25

// Plug this in for variable x in equation [1]

[1] y - 2•(-y +25) = 7

[1] 3y = 57

// Solve equation [1] for the variable y

[1] 3y = 57

[1] y = 19

// By now we know this much :

y = 19

x = -y+25

// Use the y value to solve for x

x = -(19)+25 = 6
