Answer:
b-3x+19
Step-by-step explanation:
you have to open the bracket so 3*x=3x
3*3=9
therefore;3x+9+10=3x+19
Answer:
what line are you talking about
The answer is 3.
the equation: 4x+6+3=17
4x+9=17
subtract 9 from both sides
4x=12
x=3
check by inserting 3 as x into the original equation
4*3+6+3=17
hope this helps!
