Answer:
8x+4
Step-by-step explanation:
4(2x+1)=8x+4
-6x+3=45
-3 -3 subtract
-6x=45
Divide both sides by -6
X=-7
I think this is the answer
X=8+y
x+y=70
Rewrite the first equation to x-y=8
Copy the second equation x+y=70
Add the two equations and you get 2x=78
Therefore, x=39. Since this is the bigger number the smaller number(y) would have to be 31 because you subtract 8 from x which is 39. 39 is your answer.
