5w +8-w = 6w -2(w-4)
4w +8 = 6w -2w +8
4w +8 =4w +8
This is an identity
7m-2 = 7m+4
8y+9 = 8y-3
11-2v-3 = -2v-8
8-2v = -2v-8
Answer:
[tex]5w + 8 - w = 6w - 2(w - 4)[/tex] is an identity
Step-by-step explanation:
Lets simplify equation equation and check
[tex]5w + 8 - w = 6w - 2(w - 4)[/tex]
[tex]4w + 8= 6w- 2w+ 8[/tex]
Combine like terms
[tex]4w + 8=4w+8[/tex] Both sides are equal
[tex]7m - 2 = 8m + 4 - m[/tex]
[tex]7m - 2 = 7m + 4[/tex] both sides are not equal
[tex]8y + 9 = 8y -3[/tex] Both sides are not equal
[tex]11 - (2v + 3) = -2v - 8[/tex]
[tex]11 -2v - 3 = -2v - 8[/tex]
[tex]-2v +8= -2v - 8[/tex] both sides are not equal
