7+4(r+3)=9r-6 show work pls AND HELP ASAP

ivanzaharov [21]

$\: \: \: \: \: \:$

$= \: \: \: \: r = 5$

Step-by-step explanation:

$7 + 4(r + 3) = 9r - 6$

distribute 4 through the parentheses

$7 + 4r + 12 = 9r - 6$

add numbers

$19 + 4r = 9r - 6$

move the variable to the left hand side and change its sign

$19 + 9r = - 6$

move the constant to the right hand side and change its sign

$4r - 9 = - 6 - 19$

collect like terms

 $- 5r = - 6 - 19$ 

calculate the difference

$- 5r = - 25$

divide both sides of the equation by -5

 $= \: \: \: \: r = 5$
