To solve the equation for y, we need to isolate y on one side of the equation.
Starting with the equation:
y + 2x = 5
Subtracting 2x from both sides:
y = 5 - 2x
Now, we can substitute each value of x and solve for y:
For x = -2:
y = 5 - 2(-2)
y = 5 + 4
y = 9
For x = 0:
y = 5 - 2(0)
y = 5 + 0
y = 5
For x = 3:
y = 5 - 2(3)
y = 5 - 6
y = -1
Therefore, the values of y for x = -2, 0, and 3 are 9, 5, and -1 respectively.
Solve the equation for y. Then find the value of y for each value of x.
y + 2x = 5; x = -2,0,3
