Hi,
Work:
Equation;
[tex]10q + 3q + 5 = 2(q - 3)[/tex]
Collect like terms.
[tex]13q + 5 = 2(q - 3)[/tex]
Distribute 2 thought parenthesis.
[tex]13q + 5 = 2q - 6[/tex]
Move variable 2q to left side and change its sign and move constant +5 to right side and change its sign.
[tex]13q - 2q = - 6 - 5[/tex]
Collect like terms and calculate the difference.
[tex]11q = - 11[/tex]
Divide both sides of equation by 11 and result is:
[tex]q = - 1[/tex]
Hope this helps.
