Answer:
Step-by-step explanation:
Last option is correct
x+x+x =3x
Red colour shows value is negative
-1-1 = -2
To solve for a number x,
3x+4x-2=15
7x-2=15
7x=17
x=2 3/7
or x=~2.43
was one of your answer choices either of the first two equations?
Answer:
C
Step-by-step explanation:
Use the distributive property for the left side first
3.2=1/2q+5.65
subtract 5.65 from both sides
-2.45=1/2q
divide both sides by 1/2
q=-4.9
