Add 3x to each side: 4 = 5x + 24Subtract 24 from each side: -20 = 5xDivide each side by 5: -4 = x
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
