Hey!
To simplify the equation provided we must first start off by grouping like terms.
Original Equation :
10 + 3c + 5d - 7c + d
New Equation {Grouped Like Terms} :
3c - 7c + 5d + d + 10
Now we add similar elements.
Old Equation :
3c - 7c + 5d + d + 10
New Equation {Added Similar Elements} :
-4c + 5d + d + 10
Next we add the other similtar elements.
Old Equation :
-4c + 5d + d + 10
New Equation {Add Similar Elements} :
-4c + 6d + 10
So, this means that the equation 10 + 3c + 5d - 7c + d simplified is -4c + 6d + 10.
Hope this helps!
