Answer:
7
Step-by-step explanation:
combine like variables
(7x-4x) +2 = 23
3x+2=23
subtract 2 from both sides
3x(-2+2)= (23-2)
3x=21
divide both sides by 3
3x/3= 21/3
x=7
7x+2-4x=23,,,3x+2=23,,,3x=25,,,x=25/3
your answer would be -25.078
i hope this helps.!
-4 ( 4v - u - 6 )
You will multiply -4 with everything in the parentheses.
-16v + 4u + 24
