4(x+7)+3(2x+3)=
(4x+28)+(6x+9)=
4x+28+6x+9=
6x+4x+28+9=
10x+37

First start with distributing
4 times X = 4X
4 times 7 = 28
So: 4X + 28
3 times 2X = 6X
3 times 3 = 9
So: 6X + 9
Now your new equation is:
(4X + 28) + (6X + 9)
Next do addition of the same type of number
4X + 6X = 10X
28 + 9 = 37
So: 10X + 37
