Solve 7 + x - 15 = -2.?

7 + x = 13
x = 6
Is impossible if x ≠ 6.

7 + x - 15 = - 2
x = - 2 - 7 + 15
x = 6

Answer: x = 6—there is no match among your list of possible correct answers.

Checking:
7 + 6 - 15 = - 2
13 - 15 = - 2
- 2 = - 2

x - 8 = - 2
x = 6

I think that question must be dodgy for two answers to be obtained.

Solve:

7 + x - 15 = -2

Combine like terms:

7 - 15 = -8

-8 + x = -2

Add 8 to each side of the equation

-8 + x + 8 = -2 + 8

Combine like terms:

-8 + 8 = 0

-2 + 8 = 6

x = 6


Proof:

7 + 6 - 15

13 - 15 = -2

7 + x - 15 = - 2
x = 15 - 7 - 2
x = 6

7 + x - 15 = -2
x = -7 - 2 + 15
x = -9 + 15
x = 6

as per BODMAS(Bracket Of Division Multiplication Addition Subtraction) i get the answer of 6 but i don't know why the option is 1/3 too......

7 + x - 15 = -2
x=15-2-7=6

u confused me a lot.

if we solve 7 + x - 15 = -2

the ans will be 6.

x - 8 = -2
thus, x = 6

it must be 6 and 1/3
