Can you help me solve this equation?

Sure

Answer:

x = -2

If the steps aren't belong to the lesson that you want, just tell me the lesson title so I can get the answer for you !!!!

...

The steps

Multiply all terms by (x-3)(x+3) and cancel:

x(x+3)+2x(x−3)=18

3x2−3x=18(Simplify both sides of the equation)

3x2−3x−18=18−18(Subtract 18 from both sides)

3x2−3x−18=0

3(x+2)(x−3)=0(Factor left side of equation)

x+2=0 or x−3=0(Set factors equal to 0)

x=−2 or x=3

Check answers. (Plug them in to make sure they work.)

x=−2 (Works in original equation)

x=3 (Doesn't work in original equation)

3/2+×= -7/2 i. dont know how to solve for x i dont know the answer
GuDViN [60]
So you have to get x by itself first, but you have to do the same thing on both sides in order for it to stay equal. 
3/2*2/3+x=-7/2*2/3
6/6+x=-14/6
x=-14/6
Simplify.
x=-7/3 or -2 1/3

Hope this helps! If you have any questions, just ask!

Solve for x. Round your answer to the nearest hundredth.
Doss [256]

the answer is d

because 15.56x-200 less than 758.92

collect like terms.

15.56x greater than758.92+200

it changes because when we exchange values the sign changes.

so 15.56x greater than 958.92

then we divide both sides by 15.56

and we get x greater than 61.63.

7. 21 and 22 are vertical angles. If mZ1 = (17x + 1)' and m22
olga nikolaevna [1]

Answer:

Step-by-step explanation:

Vertically opposite angles are equal.

m∠2 =  m∠1

20x - 14 = 17x + 1

Add 14 to both sides

20x = 17x + 1 + 14

20x = 17x + 15

Subtract 17x from both side

20x - 17x = 15

3x = 15

Divide both sides by 3

x = 15/3

x = 5

∠1 = 17x + 1 = 17*5 + 1 =  85 + 1 = 86

∠2 = 20x - 14 = 20*5 - 14 = 100 - 14 =86
