5x+3+x=24 6x+3=24 6x=21 x=3.5
To solve for x you would first subtract 24 from each side. You would then divide both sides by 2. The answer is x=(y-24)/2
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
15 + n = 24 (subtract 15 from both sides) n = 9
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
