Question

Resolver las operaciones con radicales a. x+1=2x-7
B. 6x+6=4+8x
C. 9+9x=17+5x​

Answer 1

Explicación paso a paso:

$x + 1 = 2x - 7 \\ 7 + 1 = 2x - x \\ 8 = x$

8+1=2*8-7

9=16-7

9=9

$6x + 6 = 4 + 8x \\ 6x - 8x = 4 - 6 \\ - 2x = - 2 \\ 2x = 2 \\ x = \frac{2}{2} = 1$

6*1+6=4+8*1

6+6=4+8

12=12

$9 + 9x = 17 + 5x \\ - 5x + 9x = 17 - 9 \\ 4x = 8 \\ x = \frac{8}{4} = 2$

9+9*2=17+5*2

9+18=17+10

27=27
