Question 61410
v - 6 = 23
v-6+6=23+6
v=29
:
Check does the equation = when v=29?
29-6=23
23=23 We're right!!!
:
2T + 5T - 3 = 11
7T-3=11
7T-3+3=11+3
7T=14
7T/7=14/7
T=2
:
Check does the equation = when T=2?
2(2)+5(2)-3=11
4+10-3=11
11=11 We're right again!!!
:

{{{X/4+9=21}}}
{{{X/4+9-9=21-9}}}
{{{X/4=12}}}
{{{4X/4=4(12)}}}
{{{X=48}}}
:
Check does the equation = when x=48?
{{{48/4+9=21}}}
12+9=21
21=21  We're right agian!!!
:
Don't try and do short cuts until you have the basics down, otherwise, when the problems get harder, you won't be able to do them and you'll get behind quickly.
Happy Calculating!!!
