Answer:
Step-by-step explanation:
x + 2y = 7
Given: x =8
To find: The value of y
x + 2y = 7
8 + 2y = 7 (Substituting the value of x in the equation)
8 - 8 + 2y = 7 - 8 (Subtracting both the sides by 8)
2y = -1
[tex]\frac{2y}{y}[/tex] = [tex]\frac{-1}{2}[/tex] (Dividing both the sides by 2)
y = [tex]\frac{-1}{2}[/tex]
