Respuesta:
espero te ayude :)
Explicación paso a paso:
1). 6a -2=4a+12
6a-4a = 12+2
2a = 14
a= 14/2
a= 7
2). 7W-18=5W+8
7W-5W = 8+18
2W = 26
W= 26/2
W= 13
3). 4e+5=2e+9
4e-2e =9-5
2e = 4
e = 4/2
e= 2
4). 6t+8=5t+17
6t-5t = 17-8
t = 9
5). 7u+2=5u+26
7u-5u = 26-2
2u = 24
u = 24/2
u =12
6). 12P=7P+20
12P - 7P = 20
5P = 20
P= 20/5
P =4
7). 13d-28=8+12
13d = 8 + 12 + 28
13d = 48
d = 48 / 13
d = 3.69 = se redondea d= 3.7
8). 2.5f-5=1.5f+10
f = 10 + 5
f= 15
9). 5/6 Y=1/2 Y+2/3
5/6 Y - 1/2 Y = 2/3
1/3 Y = 2/3
Y = 2/3 entre 1/3
Y = 1/3
6a -2=4a+12
6a - 4a = 12 + 2
2a = 14
a = 14/2
a = 7
7W-18=5W+8
7W - 5W = 8 + 18
2W = 26
W = 26/2
W = 13
4e+5=2e+9
4e - 2e = 9 - 5
2e = 4
e = 4/2
e = 2
6t+8=5t+17
6t - 5t = 17 - 8
t = 9
7u+2=5u+26
7u - 5u = 26 - 2
2u = 24
u = 24/2
u = 12
12P=7P+20
12P - 7P = 20
5P = 20
P = 20/5
P = 4
13d-28=8+12 (no se si aqui te faltó colocar una variable en la igualdad)
13d = 20 + 28
13d = 48
d = 48/13
2.5f-5=1.5f+10
2.5f - 1.5f = 10 + 5
f = 15
5/6 Y=1/2 Y+2/3
5/6Y - 1/2Y = 2/3
5/6Y - 3/6Y = 2/3
2/6Y = 2/3
1/3Y = 2/3
Y = 2/3 / 1/3
Y = 6/3
Y = 2
