Step-by-step explanation:
1) Collect like terms.
2) Simplify.
So, therefor, the answer is -17y - 16z + 4.
Answer:
-0.04x+0.9
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
10 x 3 = 30
I'll assume the above equation is: 9 - 7x = 7 - 4(2x+3)
* do distributive multiplication
9 - 7x = 7 - 8x - 12
*move like terms
-7x + 8x = 7 - 12 - 9
* solve for x
x = 7 - 21
x = -14
To check, substitute x by its value -14
9 - 7x = 7 - 4(2x+3)
9 - 7(-14) = 7 -4[2(-14) + 3]
9 + 98 = 7 - 4(-28 +3)
107 = 7 - 4(-25)
107 = 7 + 100
107 = 107
Answer:
the answer is <3 and 5
because they add up to 180
