Answer 2

Solve the Equation :

• ${ \sf \dfrac{9p + 7}{2} - \left(1 + p - \dfrac{p - 2}{7} \right) = 35}$

Step by step Explanation

${ \: \: \: \: \: : \implies\sf \dfrac{9p + 7}{2} - \left(1 + p - \dfrac{p - 2}{7} \right) = 35}$

${ \: \: \: \: \: : \implies\sf \dfrac{9p + 7}{2} - \left( \dfrac{7 +7 p - (p - 2)}{7} \right) = 35}$

${ \: \: \: \: \: : \implies\sf \dfrac{9p + 7}{2} - \left( \dfrac{7 +7 p - p + 2}{7} \right) = 35}$

${ \: \: \: \: \: : \implies\sf \dfrac{9p + 7}{2} - \dfrac{9+6 p }{7} = 35}$

${ \: \: \: \: \: : \implies\sf \dfrac{7(9p + 7) - 2(9 + 6p)}{2 \times 7} = 35}$

${ \: \: \: \: \: : \implies\sf \dfrac{63p + 49 - 18 - 12p}{14} = 35}$

${ \: \: \: \: \: : \implies\sf 51p + 31 = 35 \times 14}$

${ \: \: \: \: \: : \implies\sf 51p + 31 =4 90}$

${ \: \: \: \: \: : \implies\sf 51p = 490- 31}$

${ \: \: \: \: \: : \implies\sf \cancel{ 51} ^{1} p = \cancel{ 459}} ^{9}$

${ \: \: \: \: \: : \implies\bf p = 9}$

Verification:

${~~~~~~~~~~ \mapsto\tiny \sf \dfrac{9p + 7}{2} - \left(1 + p - \dfrac{p - 2}{7} \right) = 35}$

• Putting p=9

${~~~~~~~~~~\mapsto \tiny \sf \dfrac{9 \times 9 + 7}{2} - \left(1 + 9 - \dfrac{9 - 2}{7} \right) = 35}$

${~~~~~~~~~~\mapsto \tiny \sf \dfrac{81+ 7}{2} - \left(10 - \dfrac{7}{7} \right) = 35}$

${~~~~~~~~~~\mapsto \tiny \sf \dfrac{88}{2} - \left(10 - 1 \right) = 35}$

${~~~~~~~~~~\mapsto \tiny \sf 44 - 9 = 35}$

$~~~~~~~~~~{\mapsto \tiny \sf 35= 35} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:~~~~~~~~~ \: \: \: \: \\ \bf verified$

Step To Solve Liner Equation

In One Variable.

Step 1: Simplify each side, if needed.

Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.

Step 3: Use Mult./Div. Properties to remove any values that are in front of the variable.

Step 4: Check your answer.
