WebTo solve the equation for different variables step-by-step clear any fractions by multiplying both sides of the equation by the LCM of the denominators. Get all the terms with the … WebFeb 20, 2011 · 3-6x = 4-6x Then add 6x to both sides. 3-6x+6x = 4-6x+6x The -6x+6x becomes zero 3-0 = 4-0 And subtract the 0 from each sides 3=4 3 does not equal 4, so this is a false statement. This means the problems has no solution. No matter what number you put in for x, the original equation can never be true. So the answer is "No solution"

Solving quadratic equations by factoring (article) Khan Academy
WebStep 1: Find the value of one of the variables using any one of the equations. In this case, let us find the value of 'x' from equation (1). x + y = 6 --------- (1) x = 6 - y Step 2: Substitute the value of the variable found in step 1 in the second linear equation. Now, let us substitute the value of 'x' in the second equation 2x + 4y = 20. WebStep-by-step solution. Solving quadratic equations by completing the square. 1. Move all terms to the left side of the equation. Subtract -2 from both sides: Simplify the expression. 2. Find the coefficients.
