Question

3(2x+5) +7/2 = 4(x-2) + 11/2​

Answer 1

Answer:

$3(2x + 5) + \frac{7}{2} = 4(x - 2) + \frac{11}{2}$

$6x + 15 + \frac{7}{2} = 4x - 8 + \frac{11}{2}$

$6x + \frac{30 + 7}{2} = 4x + \frac{ - 16 + 11}{2}$

$6x + \frac{37}{2} = 4x - \frac{5}{2}$

$6x - 4x = \frac{ - 5}{2} - \frac{37}{2}$

$2x = \frac{ - 42}{2}$

$x = \frac{ - 42}{2 \times 2}$

$x = \frac{ - 21}{2} \: \: or \: \: x = - 10.5$
