Tiana solved the equation -2(3x - 5) = 4(x + 3) + 8. When
she double checked her work
by substituting, it made the
equation untrue.

actually when I solved it ,the equation is true

Step-by-step explanation:

look

-2 (3x - 5) = 4(x + 3) + 8

-6x + 10 = 4x + 12 + 8

-6x + 10 = 4x + 20

-6x - 4x = 20- 10

-10x = 10

x = -1

and when I substitute, I get 16 on both sides so I don't know where the problem is

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
