Answer 1

Simplifying

4x + -7y = 9

Solving

4x + -7y = 9

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.

4x + -7y + 7y = 9 + 7y

Combine like terms: -7y + 7y = 0

4x + 0 = 9 + 7y

4x = 9 + 7y

Divide each side by '4'.

x = 2.25 + 1.75y

Simplifying

x = 2.25 + 1.75y
