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
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
12 - 3x = 24 - 10x so 7x = 12 making x = 12/7 or one and five-sevenths.
3x + 12 + 10x = 13x + 12
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
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+15 = 7x-21 10x-7x = -21-15 3x = -36 x = -12 Which is the solution to the above equation when simplified.
-10x-6 = -12 -10x = -12+6 -10x = -6 x = 3/5
6x - 3x = 5x - 10x + 12 6x - 3x - 5x + 10x = 12 8x = 12 8x/8 = 12/8 x = 12/8 = 3/2 x = 1.5
