Respuesta:
a) 4
b) b = 9
c) a = [tex]\frac{-2}{3}[/tex]
d) x = 3
e) a = -4
Explicación paso a paso:
a) [tex]\frac{5x}{10} = 2[/tex] // 5x = 20 // [tex]x = \frac{20}{5} = 4[/tex]
b) 3b - 4 = 22 + 1 // 3b = 27 // b = 27/3 // b = 9
c) 2 + 10 + 3a = 10 // 3a = -2 // a = [tex]\frac{-2}{3}[/tex]
d) 20x = 60 // x = 60/20 // x = 3
e) [tex]\frac{6a}{2} = -12[/tex] // 6a = -24 // a = -24/6 // a = -4
