Give answer correct to two decimal answer.

Answer 1

Answer:

3.75

Step-by-step explanation:

$2x -  \dfrac{1}{2}  = 7\\\\\\\implies 2x = 7 + \dfrac{1}{2}\\\\\\\implies 2x = \dfrac{14+1}{2} = \dfrac{15}{2}\\\\\\\implies x = \dfrac{15}{2} \div 2 = \dfrac{15}{2 \times 2} = \dfrac{15}{4} = \dfrac{15 \times 25}{4 \times 25} = \dfrac{375}{100}\\\\\\= \boxed{\bold{3.75}}$

Answer 2

Given,

${2x - \frac{1}{2} = 7}$

==> ${2x = 7 + \frac{1}{2}}$

==> ${2x = \frac{15}{2}}$

==> ${x = \frac{15}{4}}$

==> ${x = 3.74}$

Therefore, your answer

${\huge{\green{\boxed{\boxed{x = 3.75}}}}}$
