Answer 5

i dont understand @pooja195

Answer 6

like that

Answer 7

yeah i know that
so it would be 10x-15? @pooja195

Answer 8

Answer 18

distribute
9(3x – 16)

Answer 19

27x-144? @pooja195

Answer 20

good
27x-144+15=6x – 24
combine like terms

Answer 21

21x-105? @pooja195

Answer 22

no
-144+15=?

Answer 23

21x-129*? @pooja195

Answer 24

Step 1: Simplify both sides of the equation.
27x−144+15=6x−24
Simplify: (Hide steps)
Let's simplify step-by-step.
27x−144+15=6x−24
27x+−144+15=6x+−24
(27x)+(−144+15)=6x−24(Combine Like Terms)
27x+−129=6x−24
27x−129=6x−24
Step 2: Subtract 6x from both sides.
27x−129−6x=6x−24−6x
21x−129=−24
Step 3: Add 129 to both sides.
21x−129+129=−24+129
21x=105
Step 4: Divide both sides by 21.
