-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
12 - 3x = 24 - 10x so 7x = 12 making x = 12/7 or one and five-sevenths.
3x + 12 + 10x = 13x + 12
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
12 - 3x = 24 - 10x so 7x = 12 making x = 12/7 or one and five-sevenths.
Though 10x +24 is an expression and it can not be evaluate, we can write 10x+24=2 • (5x + 12)
5=4x 1.25=x
3x + 12 + 10x = 13x + 12
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
-10x-6 = -12 -10x = -12+6 -10x = -6 x = 3/5
x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3
6x - 3x = 5x - 10x + 12 6x - 3x - 5x + 10x = 12 8x = 12 8x/8 = 12/8 x = 12/8 = 3/2 x = 1.5
If: y = 10x -12 and y = x^2 +20x +12 Then: x^2 +20x +12 = 10x -12 Transposing terms: x^2 +10x +24 = 0 Factorizing: (x+6)(x+4) = 0 => x = -6 or x = -4 Points of intersection by substitution are at: (-6, -72) and (-4, -52)
-4 = 17x so x = -4/17
