Question

ecuaciones x-3= -1

x-3=-5
2 x = 4
3x =-9
3x -10 = -1

- x -2 = -7
- 4x =12
4x+2 = x+8

Answer 1

a)
$x - 3 = - 1 \\ x = - 1 + 3 \\ x = + 2$
b)
$x - 3 = - 5 \\ x = - 5 + 3 \\x = - 2$

c)
$2x = 4 \\ x = 4 \div 2 \\ x = 2$

d)
$3x = - 9 \\ x = - 9 \div 3 \\ x = - 3$

d)
$3x - 10 = - 1 \\ 3x = - 1 + 10 \\ 3x = 9 \\ x = 9 \div 3 \\ x = 3$

e)

$- x - 2 = - 7 \\ - x = - 7 + 2 \\ - x = - 5 \\ x = - 5 \div ( - 1) \\ x = + 5$

f)

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


g)

$4x + 2 = x + 8 \\ 4x - x = + 8 - 2 \\ 3x = + 6 \\ x = 6 \div 3 \\ x = 2$

espero haberte ayudado
