Answer:
the first answer choice 4/16.
Answer:
4
-
9
Step-by-step explanation:
Equation
Let the number = x
2*(x + 9) = x - 8
Solve
2(x + 9) = x - 8 Remove the brackets on the left
2x + 18 = x - 8 Subtract x from both sides
2x - x + 18 = - 8 2x and - x will combine
x + 18 = - 8 Subtract 18 from both sides
x = -8 - 18
x = - 26
Check
<em>LHS</em>
2(-26 + 9)
2(-17)
-34
<em>RHS</em>
x - 8
-26 - 8
- 34 and the RHS = LHS and they check
