Question

Primul ex:4x-3=2x+9
Al doilea:
$\frac{x}{6 } = \frac{4}{12}$
Al 3 lea=
${( - 1)}^{2} + {( - 1)}^{3} + {( - 2)}^{5} - {2018}^{0}$
URGENT!

Answer 1

1.) 4x-3= 2x+9
4x-2x= 9+3
2x= 12
x= 12/2
x= 6


2.)
$\frac{x}{6} = \frac{4}{12} \\ x = \frac{6 \times 4}{12} = \frac{24}{12} = 2$

3.)
${( - 1)}^{2} + {( - 1)}^{3} + {( - 2)}^{5} - {2018}^{0} = \\ 1 + ( -1 ) + ( - 32) - 1 = \\ 1 - 1 - 32 - 1 = - 33$
