2.4x + 3.1 = 1.2x - 4.1
Subtract 1.2x from both sides: 1.2x + 3.1 = - 4.1
Subtract 3.1 from both sides: 1.2x = - 7.2
Divide both sides by 1.2: x = -6
x2 + 24x +180 = 0 By using the quadratic equation, you can find that x = -12 + 6i or x = -12 - 6i
7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
4(3x-8y = 24) 12x+32y = 96 Multiply all terms in the first equation by 4: 12x-32y = 96 12x+32y = 96 Add both equations together: 24x = 192 Divide both sides by 24 to find the value of x: x = 8 Substitute the value of x into the original equations to find the value of y: Therefore: x = 8 and y = 0
x=-.25.
(x^2) + 24x + 144 = -9 x = -12
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
x2 + 24x +180 = 0 By using the quadratic equation, you can find that x = -12 + 6i or x = -12 - 6i

12x-5y+3 = 0 => y = 2.4x+0.6 24x-10y-7 => y = 2.4x-0.292 rounded to 3 d.p. Both lines have the same slope but different y intercepts therefore they are parallel to each other.
7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
