21=3*7
28=2*2*7
gcf: 7
21w+28=7(3w)+7(4)=7(3w+4)
2.
1/3p-2/3=1/3p+(-2/3)=1/3(p)+1/3(-2)=1/3(p-2)
3.
12/6=2
-42/6=-7
12y-42=12y+(-42)=6(2y)+6(-7)=6(2y-7)
Answer:
(-9,-1)
Step-by-step explanation:
See the attachment. Use a graphing system such as Desmos and find the intersection of the 2 lines.
One may also solve them mathematically to insure the correct solution.
y = (1/3)x + 2
y = (2/3)x + 5
---
Since y = y:
(1/3)x + 2 = (2/3)x + 5
-(1/3)x = 3
x = -9
---
Use this value to find y:
y = (1/3)x + 2
y = (1/3)(-9) + 2
y = -1
