Short Answer: No
2(12 - y) = 23- (2y - 1) Remove the Brackets on both sides
24 - 2y = 23 - 2y + 1 Combine like terms on the right
24 - 2y = 24 - 2y No matter what you do, the 2ys are going to cancel. When they do, the question goes with them.
You get 24 = 24 Which is true but not relevant.
The other answer you could use is there are an infinite number of answers.
Equality will be maintained, but there is no single answer that works.
The closest to 13 is because 13.09≈13
Answer:
3y + 4 = 20 + y

Answer: See explanation
Step-by-step explanation:
Let the base be represented by x.
Therefore, the height will be = 3 × x = 3x
Since Area of a triangle = 1/2 × base × height
1/2 × x × 3x = 73.5
3x²/2 = 73.5
3x² = 73.5 × 2
3x² = 147
x² = 147/3
x² = 49
x = ✓49
x = 7
Base = 7cm
Height = 3 × 7 = 21cm
