10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
x = 6 and 2/7
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
x2 + 10x + 21 = (x + 3)(x + 7)
10x+7=(-3) 10x=(-10) x=(-1)ans

10x ÷ 2 = 7 → 10x = 2 × 7 → x = (2 × 7) ÷ 10 → 2x = 2 × (2 × 7) ÷ 10 = 2.8
7x = 3 x = 3/7
x=-3
