Ayuda :(( no puedo hacerlo es para hoy día

Answer 1

$a + (-\frac{8}{3} ) = 23\\\\3a -8 = 69\\3a = 69 + 8\\3a = 77\\a = 77/3$  

$2y + (-\frac{5}{4}) = 0 ,75\\\\2y + (-\frac{5}{4}) = \frac{75}{100}\\\\2y + (-\frac{5}{4}) = \frac{3}{4}\\\\2y -\frac{5}{4} = \frac{3}{4}\\\\2y = \frac{3}{4} + \frac{5}{4}\\\\2y = \frac{8}{4} \\\\2y = 2\\\\y = 2/2\\\\y = 1$
