Answer:

5

Step-by-step explanation:

this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5

3x + 2 =11 (solve for x)
torisob [31]

Answer:

x=3

Step-by-step explanation:

first let's try to get just 3x on one side. to do this we can subtract 2 from both side of the equation.

3x+(2-2)=11-2

3x=9

now we have to isolate the variable we can divide both sides by 3:

3x/3=9/3

x=3

and you get the answer that x is 3

Answer: x\leq 3

PLEASE MARK ME BRAINLIEST

Step-by-step explanation:

1) Simplify both sides of the inequality:

4x+8\geq 5x+5

2) Subtract 5x from both sides:

4x+8-5x\geq 5x+5-5x

3) Simplify:

-x+8\geq 5

4) Subtract 8 from both sides:

-x+8-8\geq 5-8

5) Simplify:

-x\geq -3

6) Divide both sides by -1:

\frac{-x}{-1} =\frac{-3}{-1}

7) Simplify:

x\leq -3
