p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; color: #454545} p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; color: #454545; min-height: 14.0px}

Simplifying

3x + 7y = 28

Solving

3x + 7y = 28

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 = 28 + -7y

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

3x + 0 = 28 + -7y

3x = 28 + -7y

Divide each side by '3'.

x = 9.333333333 + -2.333333333y

Simplifying

x = 9.333333333 + -2.333333333y
