Question

4m-5(m+2)=1
Will somebody please help me solve this, solve for m and the 5 is subtraction.

Answer 1

thank you

Answer 2

isn't it m=-11

Answer 3

Typo,

4m-5(m+2)=1

4m - 5m -10 = 1

-m - 10 = 1
+10 +10

-m = 11
/-1 /-1

M= -11



4(-11)-5(-11+2)=1

-44 +55 + 10 = 1

11 - 10 = 1

1 = 1 so this is true

Answer 4

how did you figure that out? i might need to know for future reference.

Answer 5

I applied distributive property to -5(m+2)

4m - 5m -10 = 1

Then you combine like terms, 4m-5m = -1m or just -m

-m - 10 = 1

You want to isolate m, so the inverse of subtraction is addition, add 10 to both sides

-m = 11

m can't be negative so divide by -1

-m = 11
/-1 /-1

m = -11
