$26 x - 3 y$ $26x-3y$

$(18 x - 9 y) + 8 x + 3 (20 y \div 10)$ $(18x -9y) +8x +3(color(red)(20ydiv10))$

= $18 x - 9 y + 8 x + 3 (2 y) \leftarrow$ $18x-9y +8x +3(color(red)(2y))" "larr$ re-arrange like terms

= $18 x + 8 x - 9 y + 6 y$ $18x+8x-9y+6y$

= $26 x - 3 y$ $26x-3y$

How do you simplify (18x−9y)+8x+3(20y÷10)(18x-9y)+8x+3(20ydiv10)?
