Answer:
it is -12, -6, -4, -3, 1, 4
12(20-17) - 3*6
12 (3) - 18
12*3 - 18
36 - 18
18
Hello!
First:
write an equation.
5x + (7x+8) + (7x+2) = 143
now combine like terms
19x + 10 =143
now subtract 10 from both sides
19x = 133
divide 19 on both sides.
x = 7.
Are you done here? Nope, we need to find out what each side is, so lets plug in the number 7 for x.
-----------------------------
For the side 5(x)
5(7) = 35
This side is 35m
-----------------------
For the side 7x + 2
7(7) + 2
49 + 2
51
This side is 51m
------------------------
For the side 7x + 8
7(7) + 8
49 + 8
57
This side is 57m.
------------------------
I hope this helps,
Have a great day!
