Question

9x+17-6=4x+26
11x+14-7x-5=39-x
4x+1+2(5+x)=x+71
3x2+6x=15+2x+11
5(x+3)-11=2x+19
21+3(2x-2)-2x=60-x

Answer 1

9x+17-6=4x+26
9x + 11 = 4x + 26
9x - 4x = 26 - 11
5x = 15
X = 15/5
X = 3

11x+14-7x-5=39-x
4x + 9 = 39 - x
4x + x = 39 - 9
5x = 30
X = 30/5
X = 6

4x+1+2(5+x)=x+71
4x + 1 +10 +2x = x +71
6x + 11 = x + 71
6x - x = 71-11
5x = 60
X = 60/5
X = 12

3x2+6x=15+2x+11
3x² + 4x - 26 = 0
X =( - 2-√82)/3
X = (2+√82)/3

5(x+3)-11=2x+19
5X + 15 - 11 = 2X +19
5X +4 = 2X + 19
5X - 2X = 19-4
3X = 15
X = 15/3
X = 5

21+3(2x-2)-2x=60-x
21 + 6X - 6 - 2X = 60 - X
15 +4X = 60-X
4X +X = 60 - 15
5X = 45
X = 45/5
X = 9
