Question

con procedimiento por favor

Answer 1

1)
2*(3x+5) = 82
6x + 10 = 82
6x = 82-10
6x = 72
x = 72/6
x = 12

2)
4+4x = 2*(5x-x)
4+4x = 2*4x
4+4x = 8x
4x-8x = -4
-4x = -4
x = -4/-4
x = 1

3)
2*(2x+8) = 5x
4x+16 = 5x
4x-5x = -16
-x = -16
x = 16

4)
3*(3x+6) = 10x
9x+18 = 10x
9x-10x = -18
-x = -18
x = 18

5)
4*(4x+6) = 18x
16x + 24 = 18x
16x-18x = -24
-2x = -24
x = -24/-2
x = 12

6)
2+2x = 3*(4x-3x)
2+2x = 3*x
2x-3x = -2
-x = -2
x = 2

7)
3+3x = 2*(2+x)
3+3x = 4+2x
3x-2x = 4-3
x = 1

8)
5*(5-x) = 2*(2+x)
25-5x = 4 + 2x
-5x-2x = 4-25
-7x = -21
x = -21/-7
x = 3
