Can someone explain? i don't understand
6(2x – 11) + 15 = 3x + 12
part a: write the steps you will use to solve the equation, and explain each step. (6 points)
part b: what value of x makes the equation true? (4 points)

6(2x-11)+15=3x+12 Given

12x-66+15=3x+12 Distribution

12x-51=3x+12 Combine like terms

12x=3x+63 addition

9x=63 subtraction

x=7 division

the value of x that makes the equation true is 7.

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
