Respuesta:
a ) x = 6
b ) x = 10
c ) x = 2
d ) t = 9
e ) b = 2
f ) r = 1
g ) x = 24
Explicación paso a paso:
a )
12 = 6 + x
6 + x = 12
x = 12 - 6
x = 6
b )
x - 7 = 3
x = 3 + 7
x = 10
c )
6x - 2x = 8
4x = 8
x = 8 / 4
x = 2
d )
36 = t . 4
t = 36 / 4
t = 9
e )
2 ( b + 2 ) + 5 ( b - 3 ) = 3
2b + 4 + 5b - 15 = 3
2b + 5b + 4 - 15 = 3
7b - 11 = 3
7b = 3 + 11
7b = 14
b = 14 / 7
b = 2
f )
6r + 12r - 9 - 8r + 10 + r = 12
6r + 12r + r - 8r + 10 - 9 = 12
19r - 8r + 1 = 12
11r = 12 - 1
11r = 11
r = 1
g )
50 = 2x + 8
2x = 50 - 8
2x = 48
x = 48 / 2
x = 24
solo puedo ayudarte en esas, lo siento
