Answer:
Therefore, when we put x=1 and y=2, the equation 3(x+2y)-2x+10 simplifies to 23.
Explanation:
To evaluate and simplify the expression first we have to put x=1 and y=2 in the equation as given in the question,
3(x+2y)-2x+10 = 3(1+2(2))-2(1)+10
=3(1+2(2))-2+10
= 3(1+4)+8
= 3(5)+8
= 15+8
= 23
Therefore, when we put x=1 and y=2, the equation 3(x+2y)-2x+10 simplifies to 23.
