Respuesta:
a) -5
b) 6
c) -4
d) -2
e) 2
Explicación paso a paso:
a) 8y +27 = 2y -3
8y + -2y = -3 -27
6y = -30
y = [tex]\frac{-30}{6}[/tex]
y = -5
b) 7b - 8 = 5b + 4
7b -5b = +4 +8
2b = 12
b = [tex]\frac{12}{2}[/tex]
b = 6
c) h + 9 = -3h -7
h +3h = -7 -9
4h = -16
h = [tex]\frac{-16}{4}[/tex]
h = -4
d) -3a +8 = 5a +24
-3a -5a = +24 -8
-8a = 16
a = [tex]\frac{16}{-8}[/tex]
a = -2
e) 8x -5 = 6x -1
8x -6x = -1 +5
2x = 4
x = [tex]\frac{4}{2}[/tex]
x = 2
