REZOLVA in MULTIMEA z ECUATIILE​

Answer 1

Explicație pas cu pas:

$17 + x = 1 \\ x = 1 - 17 \\ x = - 16$

$x + 39 = 0 \\ x = - 39$

$- x - 7 = 0 \\ - x = 7 \\ x = - 7$

$- x + 12 = - 1 \\ - x = - 1 - 12 \\ - x = - 13 \\ x = 13$

$x - 43 = 11 \\ x = 11 + 43 \\ x = 54$

$12 - x = 5 \\ - x = 5 - 12 \\ - x = - 7 \\ x = 7$

$- 13 + x = - 1 \\ x = - 1 + 13 \\ x = 12$

$- x + 2 + 3x = 2 \\ 2x = 2 - 2 \\ 2x = 0 \\ x = 0$

$6 + 5x = 2x + 18 \\ 5x - 2x = 18 - 6 \\ 3x = 12 \\ x = 12 \div 3 \\ x = 4$

$- 4 - 3x = x + 8 \\ - 3x - x = 8 + 4 \\ - 4x = 12 \\ x = 12 \div ( - 4) \\ x = - 3$

$- ( - x - 3) + 2 = 10 \\ x + 3 + 2 = 10 \\ x + 5 = 10 \\ x = 10 - 5 \\ x = 5$

$3 - (4 - x) = 1 \\ 3 - 4 + x = 1 \\ - 1 + x = 1 \\ x = 1 + 1 \\ x = 2$
