I need help on two problems I would like if you went step by step with the problem with me and then let me figure out the answer.

If, Tonya and Toya have $15.25 together and Tonya had 25 cents more than Toya, how much does each have?

Second question:

Bruce is 7 years older than his sister Pilar. The sum of their ages is 1 less than 3 times Pilar's age. How old is each.

Show equations for both

First problem:

X1 + X2 = 15.25

X1 - X2 = 0.25

2 X1 = 15.50

X1 = 7.75

X2 = X1 - 0.25 = 7.50

Second problem:

B - P = 7

B + P = 3P -1

B - 2P = -1

P = 8

B = P+7 = 15
