25-5=.50n

20=.50n

20/.50=.50n/50

40=n

**********

45t+10=190

45t=190-10

45t=180

45t/45=180/45

t=4

25-5=(5-5)+.50n therefore getting

20=.50n now divide both sides by .50 beacuse it is attached to the n

20/.50=.50n/.50

40=n

45t+10=190 subtract 10 from both sides

45t=(10-10)=190-10 therefore getting

45t=180 now divide both sides by 45 beacuse it is with the t

45t/45=180/45

t=4

Now to check your answers, plug in the n= and t= where the n and t are and you should come up with the first equation

25=5+(.50*40)

and

(45*4)+10=190

25=5+..50n

25 – 5 = 5 – 5 + .50n

20 = .50n

20/.50 = .50n/.50

40 = n

45t+10=190

45t = 180

t = 180/45

t = 4

first divide everything by .5 (which is the same as multiplying it by 2)

50=10+n

then subtract 10 from both sides

40=n, so n=40

45t+10=190

first subtract 10 from both sides

45t=180

then divide both sides by 45

t=4

25-5 =.50n

20 =.50n

20/.50 = n

40 = n

2)45t+10=190 solve for t

45t = 190 – 10

45t = 180

t = 180/45

t = 4

by the way SOLVE not slove LOL……

good luck in your math class

n=40

45t+10=190

t=4

then divide both sides by .50 to get 40.

for the second one basically you want to get the variable (t) by itself. pretend the equal sign divides the equation into two teams. If you take 10 people from one team take ten people from the other team. 190-10 is 180. 45t=180, divide both sides by 45 and you get 4

20=.50n

divide both sides by .50

10=n

190-10

180=45t

divide both sides by 45

4=t
