Solve: 3 + 2(x + 10) = 17. help please!?

Question

Solve: 3 + 2(x + 10) = 17.


a. x = 2

b. x = -3

c. x = 3

d. No solution

Answer 1

3 + 2(x + 10) = 17

expand the brackets 3 + 2x + 20 = 17

2x + 23 = 17

subtract 23 from both sides

2x = -6

divide both sides by 2

2x / 2 = -6 / 2

x = -3

therefore the answer is b. x= -3

Answer 2

3 + 2(x + 10) = 17
=> 2(x + 10) = 17 - 3
=> 2(x + 10) = 14
=> (x + 10) = 7
=> x = 7 - 10
=> x = -3
Answer is b, x = -3.

Answer 3

3+2(x+10)=17 3+2x+20=17 2x=17-23 2x=-6

X=-3 So the answer is b.

Answer 4

3 + 2(x + 10) = 17

=>

3 + 2x + 20 = 17

=>

2x + 23 = 17

=>

2x = -6

=>

x = -3
Answer B

Answer 5

3 + 2(x + 10) = 17 distribute 2
3+2x+20=17 combime like terms
23+2x=17 subtract 23 from each side
2x=-6 divide both sides by 2
x=-3

Answer 6

3 - 3 + 2(x+10) = 17 - 3 (Subtract 3 from both sides)
2x + 20 = 14 (Expand and simplify)
2x + 20 - 20 = 14 - 20 (Subtract 20 from both sides)
2x = -6 (Simplify)
x = -3 (Solve)

The Answer is B

Answer 7

3 + 2x+20= 17
23 +2x= 17
2x= -6
x= -3

answer B

Answer 8

3 + 2x + 20 = 17
2x = 17 - 23
2x = - 6
x = - 3
ANSWER b.

Answer 9

ok, Samantha; this would be a grimy rotten question. This "triangle" isn't in all possibility a triangle in any respect on account that to make certain that a=5 plus b=6 to equivalent 11, the factor the place a and b connect could be in line c. you're able to desire to now say that the attitude opposite the phony "hypotenuse" is one hundred eighty stages, needless to say no longer ninety stages. So..., the "triangle" isn't a top triangle and, in certainty, isn't a triangle in any respect... Dave

Since you were prepared to cheat by coming here in the first place, would it not have been simpler to have simply substituted the three possible values to see what the answer is?
