Answer:
3.666666667
Step-by-step explanation:
Simplifying
3x + -7y = 11
Solving
3x + -7y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
3x + -7y + 7y = 11 + 7y
Combine like terms: -7y + 7y = 0
3x + 0 = 11 + 7y
3x = 11 + 7y
Divide each side by '3'.
x = 3.666666667 + 2.333333333y
