Question

Ayudaaaaaaaaaaaaaaaaaaaaaaaa por favor alguien que me pueda ayudar

Answer 1

a)

$2x - 3 = - x - 9 \\ 2x + x = - 9 + 3 \\ 3x = - 6 \\ x = - 6 \div 3 \\ x = - 2$

b)

$3 = 5x - 12 \\ 3 + 12 = 5x \\ 15 = 5x \\ 15 \div 5 = x \\ 3 = x$

c)

$- 3x - 11 = x + 5 \\ - 3x - x = 5 + 11 \\ - 4x = 16 \\ x = 16 \div ( - 4) \\ x = - 4$

d)

$8x - 30 = 2x - 6 \\ 8x - 2x = - 6 + 30 \\ 6x = 24 \\ x = 24 \div 6 \\ x = 4$

e)

$11x - 15 = 12 + 2x \\ 11x - 2x = 12 + 15 \\ 9x = 27 \\ x = 27 \div 9 \\ x = 3$

f)

$x + 13 = 43 - 14x \\ x + 14x = 43 - 13 \\ 15x = 30 \\ x = 30 \div 15 \\ x = 2$
