Explicație pas cu pas:
a)
[tex](x + 2) : 3 = 4 \\ x + 2 = 4 \times 3 \\ x + 2 = 12 \\ x = 12 - 2 \\ x = 10[/tex]
b)
[tex]10 \times ( {2}^{3} - {2}^{2} - {2}^{0} ) : x = 1 \\ 10 \times (8 - 4 - 1) = x \\ x = 10 \times 3 \\ x = 30[/tex]
c)
[tex]( - {2}^{ {2}^{3} } ) = ( {2}^{ {2}^{3} } ) \times x \\ - {2}^{8} = {2}^{8} \times x \\ x = - {2}^{8} : {2}^{8} \\ x = - 1[/tex]
d)
[tex]- 2x + 10 = - 3 \\ - 2x = - 3 - 10 \\ - 2x = - 13 \\ x = \frac{13}{2}[/tex]
