we have

Step 1
Eliminate the parenthesis

Step 2
Group terms that contain the same variable

Step 3
Combine like terms

therefore
the answer is

Answer:
x = -1
Step-by-step explanation:
3(x+2)=−5−2(x−3) multiply 3 and -2 with inside the parenthesis
3x + 6 = -5 -2x + 6 now add the like terms
3x + 2x = 1 - 6
5x = -5 simplify both sides
x = -1
Answer:
-y^2 - 10 y - x^72 + -1
Step-by-step explanation:
Simplify the following:
-y^2 - 3 y - 5 - (x^36)^2 - 7 y + 4
Multiply exponents. (x^36)^2 = x^(36×2):
-y^2 - 3 y - 5 - x^(36×2) - 7 y + 4
36×2 = 72:
-y^2 - 3 y - 5 - x^72 - 7 y + 4
Grouping like terms, -y^2 - 3 y - 5 - x^72 - 7 y + 4 = -y^2 + (-3 y - 7 y) - x^72 + (4 - 5):
-y^2 + (-3 y - 7 y) - x^72 + (4 - 5)
-3 y - 7 y = -10 y:
-y^2 + -10 y - x^72 + (4 - 5)
4 - 5 = -1:
Answer: -y^2 - 10 y - x^72 + -1
-3x + 20 > = 8
-3x > = 8 - 20
-3x > = -12
x < = -12/-3
x < = 4
