Question

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

Answer 1

`\: \: \: \: \: \:`

`= \: \: \: \: r = 5`

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`

hope it helps
