Question

how to solve 2x + 3(x-1) = 7/2​

Answer 1

Step-by-step explanation:

2x + 3(x-1) = 7/2

$2x + 3x - 3 = 7 \div 2 \\ 5x - 3 = 3.5 \\ 5x = 3.5 + 3 \\ x = 6.5 \div 5 \\ x = 1.3$

Answer 2

$2x + 3(x - 1) = \frac{7}{2} \\ = 2x + 3x - 3 = \frac{7}{2} \\ = 5x = \frac{7}{2} - 3 \\ = 5x = \frac{1}{2} \\ x \ = \frac{1}{2} \times \frac{1}{5} \\ x = \frac{1}{10}$
