Answer:

$x = \frac{ - 3}{2} \: or \: \frac{1}{3}$

Step-by-step explanation:

$7 {x}^{2} + 10x - 3 = {x}^{2} + 3x$

$= > 7 {x}^{2} - {x}^{2} + 10x - 3x -3 = 0$

$= > 6 {x}^{2} + 7x - 3 = 0$

$= > 6 {x}^{2} + 9x - 2x - 3 = 0$

$= > 3x(2x + 3) - 1(2x + 3) = 0$

$= > (2x + 3)(3x - 1) = 0$

Here x will have 2 values.

1) $2x + 3 = 0$

$= > 2x = - 3$

$= > x = \frac{ - 3}{2}$

2) $3x - 1 = 0$

$= > 3x = 1$

$= > x = \frac{1}{3}$

Step-by-step explanation:

Statements Reasons

1. $\overline{AD}\parallel \overline{BC}$ Given

2. $\angle ADB\cong \angle CBD$ As alternate interior angles when parallel lines AD and BC intersect by ltransversal BD

3. $\overline{AD}\cong \overline{BC}$ Given

4. $\overline{BD}\cong \overline{DB}$ Reflexive property

5. $\triangle ADB\cong \triangle CBD$ SAS postulate

6. $\angle ABD\cong \angle CDB$ Corresponding parts of congruent triangles are congruent

7. $\overline{AB}\parallel \overline{CD}$ Inverse alternate interior angles theorem
