Insert parentheses on the left side of the equation to make the statement true for all values of p

7+5(p-p)=7
because 7+5p-5p=7
cross our the 5p because 5p-5p is 0
7=7

I need help solving #9 & #11! It's geometry but I'm just really stuck<br><br>

Vikentia [17]

Answer:

9)x=11 y=3

11)x=18 y=5

Step-by-step explanation:

9) 9x+25=13x+19 13x-19+17y+5=180

9x+44=13x 129+17y=180

44=4x 17y=51

11=x y=3

11) 49+3x=7x-23 3x=11y-1
