The graph of the equation 2x+6y=4 passes through point (x,-2). What is the value of x?
Plug -2 in for y and solve for x
To find the value of x for the point (x, -2) that lies on the graph of the equation 2x + 6y = 4, we can substitute the given coordinates into the equation and solve for x.
Step 1: Substitute the values into the equation.
2x + 6(-2) = 4
Step 2: Simplify the equation.
2x - 12 = 4
Step 3: Move the constant term to the other side of the equation.
2x = 4 + 12
2x = 16
Step 4: Divide both sides of the equation by 2 to isolate x.
x = 16/2
x = 8
Therefore, the value of x for the point (x, -2) that lies on the graph of the equation 2x + 6y = 4 is 8.
