Add 3x to each side: 4 = 5x + 24
Subtract 24 from each side: -20 = 5x
Divide 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
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
2x+a=p 2x=p-a x=.5p-.5a
x = -8
I would use substitution. Turn the second equation into y=8-2x, put it into the first and solve for x. Then put x into one of the equations and solve for y.So...2x-3(8-2x)=24 --> 2x-24+6x=24 --> 8x=48 --> x=6y=8-(2x6) --> y=8-12 --> y=-4
