Question

solve 3x+5 divided by 2x+7=4

Answer 1

Step-by-step explanation:

$2x + 7 = 4..eq(1) \\ \\ 2x = - 3 \\ \\ x = \frac{ - 3}{2} \\ \\ 3x + 5 = 3( \frac{ - 3}{2} ) = \frac{ - 9}{2} ..eq(2) \\ \\ \frac{</strong><strong>3</strong><strong>x + </strong><strong>5</strong><strong>}{</strong><strong>2</strong><strong>x + </strong><strong>7</strong><strong>} = \frac</strong><strong>{ \frac{ - 9}{2} }</strong><strong>{ </strong><strong>4</strong><strong>} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = - \frac{</strong><strong>9</strong><strong>}{</strong><strong>8</strong><strong>}$

Answer 2

Given:

= 3x+5/2x+7 = 4

= 3x+5 = 4(2x+7)

= 3x+5 = 8x+28

= 3x-8x = 28-5

= -5x = 23

= x= -23/5
