Question

Solve the equation negative 3X +9 equals three(2x+3) + 3(x-4) + 1

Answer 1

x=11/12

Explanation:

-3x+9=3(2x+3)+3(x-4)+1

distribute first

-3x+9=6x+9+3x-12+1

simplify the right side

-3x+9=9x-2

add 3x to both sides

9=12x-2

add 2 to both sides

11=12x

divide both sides by 12

x=11/12
