Answer:
hey there mate I hope this will help you :)
Step-by-step explanation:
20)t+t+3=13
2t+3=13
To find the value of t subtracting 3 on both sides
2t+3-3=13-3
2t=10
Dividing 2 on both sides
2t/2=10/2
t=5
21)3u-1=17
To find the value of u adding 1 on both sides
3u-1+1=17+1
3u=18
Dividing 3 on both sides
3u/3=18/3
u=6
22)v+v-2=12
2v-2=12
To find the value of v adding 2 on both sides
2v-2+2=12+2
2v=14
v=7
23)w-4=0
To find the value of w adding 4 on both sides
w-4+4=0+4
w=4
24)2x-10=0
To find the value of x adding 10 on both sides
2x-10+10=0+10
2x=10
x=5
25)12-3y=0
To find the value of y subtracting 12 on both sides
-3y=-12
Dividing -3 on both sides
y=-12/-3
y=4
