The answer is 66.75
I would suggest multiplying 2 in (2x+1) by 2 5/8 first, then multipling 4 by 2 5/8. This will garner you 10 and 5.25. Distribute the 9 into the (). You'll then get 10.5+47.25+9
Add and you will get 66.75

Answer:

Step-by-step explanation:





Answer:
x= -5
y= -2
Step-by-step explanation:
From the equation y=x+3-------eqn 1
x+y= -7-------eqn2
x+(x+3)= -7 (since there is no value before the bracket is 1, so multiply by 1)
x+x+3= -7
2x+3=-7
2x=-7-3
2x=-10
x=-10/2
x=-5
Insert x value in equation 1
y= -5+3
y=-2
