x = 5
4x = 20 so you have to divide both sides with 4, so that makes 4x : 4 = x 20 : 4 = 5 x = 5
-20 = -4x +6 add 20 to both sides 0 = -4x +26 4x = 26 x = 26/4 = 6.5
-4x + 6 = 26 Subtract 6 from both sides: -4x = 20 Divide both sides by -4: x = 20/-4 Solve for x: x = -5
X is 6
-20=-4x-6x -20=-10x {collect like terms} x=2 {divide each side by -10}
x=5
4x -17 equals 3 4x equals 20 x equals 5
4x = 24 x = 24 ÷ 4 x = 6
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
To solve the system of equations (4x + 8y = 20) and (-4x + 2y = -3), you can use the elimination method. First, add the two equations together to eliminate (x): [ (4x - 4x) + (8y + 2y) = 20 - 3 ] This simplifies to (10y = 17), giving (y = \frac{17}{10}). Substitute (y) back into either original equation to find (x). For example, using (4x + 8(\frac{17}{10}) = 20), you can solve for (x).
-4x-6x = -20 -10x = -20 Divide both sides by -10 rembering that a minus divided into a minus the result is positive: x = 2
7x = 20 + 4xSubtract 4x from each side of the equation:3x = 20Divide each side by 3 :x = 20/3
