2x+3(x+4) = -11

If you can answer this, that would be awesome!! :))

x= -23/5

alternative form:

x= -4.6 or x= -4 3/5

Step-by-step explanation:

2x+3(x+4)= -11

multiply numbers in parenthesis by 3

2x+3x+12= -11

add 2x to 3x

5x+12= -11

move constant to right

5x= -11-12

subtract -11 to -12 but since there both negative the equation is addition.

5x= -23

divide both sides by 5

x= -23/5

alternative form:

x= -4.6 or x= -4 3/5

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
