Simplify Apply the distributive method 3x+9-11=x+6 3x-2=x+6 move all with x on the left and not containing x on the right
3x-x=6+2 subtract 2x=8 Divide and simplify X=8/2 X+4
UngradedGrade: 0/1.0
Feedback: Apply standard algebraic properties
3(x+3) -11=x+6
3x+9-11=x+6
Apply the distributive property
3x-2 =x+6
Combine like terms.
2x=8
Place x- terms on one side and simplify
8 r = 2
x =4
