Improved Answer:-If: 20x+27 = 143Then: x = 5.8
20X - 3 + 3X = 11X + 5 - 8 put those like terms together on the left 23X - 3 = 11X + 5 - 8 like terms together on the right 23X - 3 = 11X - 3 this equation admits of no solution, so is not true X would = 0
To solve for 2 unknown variables you need at least 2 independent equations. You have only 1.
2x + 20x = 111,45222x = 111,452x = 5,066
