Not sure how the this works out. Please show computations:. 5(x+2) - (2x-3) =?

Multiply 5 by the first parenthesis, multiply the second paren by -1.





5(x+2) - (2x-3)





becomes


5x+10 -2x + 3Not sure how the this works out. Please show computations:. 5(x+2) - (2x-3) =?
= 5x + 10 - 2x + 3


= 3x + 13Not sure how the this works out. Please show computations:. 5(x+2) - (2x-3) =?
5(x+2) - (2x-3)





1) Remove the brackets first


10x+10-2x+3


2) Group terms


10x-2x + 10+3


3) Compute


8x + 13
5(x+2)-(2x-3)=0


5x+10-2x+3=0


3x+13=0


3x=-13


x=-13/3
