<h2>m= - 3</h2>

Step-by-step explanation:

3-2(9+2m)=m (we multiply 2 by each term inside the parenthesis)

3 - (18 + 4m) =m

3 - 18 - 4m =m

-15 - 4m - m =0 (we bring m before the equal)

-15 - 5m =0

-5m =15

m = 15 /-5

m =  - 3

hope \: this \: helps..good \: luck

Answer:

m = -3

Step-by-step explanation:

3-2(9+2m)=m

3-18-4m=m

<em>Add 4m to both sides</em>

3-18=5m

-15=5m

<em>Divide both sides by 5</em>

-3=m

m= -3

If the difference of two numbers is 7 and their product is 60, what are they?
user100 [1]
X - y = 7.....x = y + 7
x * y = 60

y(y + 7) = 60
y^2 + 7y = 60
y^2 + 7y - 60 = 0
(y + 12)(y - 5) = 0

y + 12 = 0
y = -12....not this one because it is negative

y - 5 = 0
y = 5 <===

x - y = 7
x - 5 = 7
x = 7 + 5
x = 12 <==

so ur 2 numbers are 12 and 5
