if you want working then first we multiply both sides by (a+b) to get ma+mb=ab
then subtract ma from both sides to get mb=ab-ma then factorise a to get mb=a(b-m) then divide both sides by b-m to get mb/b-m = a

ok that kinda made sense

how about these two?

15/x + 10 = 35/4x

3T + 7PM/T = 13 - P

eh times both sides by 4x gives you 60+40x=35
40x=-25
x=-25/40
simplifys to what i said
and are you sure it asks for t because that shits impossible

Solve the following formula for the variable T. Verify your solution.

3T + 7PM / T = 13 - P

Thats how its written

if its the second the answer is as follows 3t+7pm/t=13-p
times through by t gives us 3t+7pm=13t-pt
subtract 3t from both sides
7pm=13t-pt-3t
which goes to
10t-pt=7pm
which factorises to t(10-p)=7pm
which is t=7pm/(10-p)

hope thats what you wanted

[15/(-5/8 )]+10 = -14

how?

15/-.625 = -24+10 = -14

35/4(-.625) = -5.46

unless im doing something wrong?

isolate the variable "w". by moving -19/2 and 1/10 to the other side of the equation. combine like terms. solve for w.
