4 (2x – 3)= 2( 3x + 1)
<span>(4 (2x – 3)= 2( 3x + 1)) </span>÷ 2
2 (2x – 3) = (3x + 1)
4x - 6 = 3x +1
-3x -3x
__________
x - 6 = 1
+6 +6
______
x = 7
Answer:
B
Step-by-step explanation:
Given
- 3x + 12 ≤ 15 ( subtract 12 from both sides )
- 3x ≤ 3
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x ≥ - 1
Since x can equal - 1, we are looking for a solid circle at x = - 1 on the number line.
Since x greater than - 1 we require the shaded arrow to be pointing right.

Answer:
5 years
Step-by-step explanation:
1. if able's age is x, then his sister's is x-4, and his brother's is 2x
2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32
3. now solve for x, 4x-4=32, 4x=36, x=9
4. if able's sister is x-4 years old, she is 9-4, or 5 years old
