Answer:
Step-by-step explanation:
1. Rearrange the equation( actually all of them)
Take left hand side to the right for 1st question
1+5v+3+v-5-4v=0
2v+1=0
2v=-1
v=-1/2
2. Multiply RHS
15-x=2x+6
Move LHS to the right
2x+6-15+X=0
3x-9=0
3x=9
Divide both sides by 3
We get X=3
3.I'll leave the third one for you it's the same as second .
4.move RHS to the right (actually you can move any side but I'm trying to avoid a negative sign by moving the smaller to the side of the bigger number)
6m-11=2+9m-1
2+9m-1-6m+11=0
3m+12=0
m=-4
