a.4

b.5

c.6

d.7

​

Answer 1

Answer:

your ans==>7

Step-by-step explanation:

$\sf\red{π(x) + 3y = 25 \: and \: y = 1 } \\ \\ \sf\purple{\implies \pi x+ 3 \times 1 = 25} \\ \\ \sf\purple{\implies \: x = \frac{25 - 3}{ \pi} } \\ \\ \sf\purple{ \implies \: x = \frac{22}{ \frac{22}{7} } \: \: \: \: \: \: \boxed{ \pi = \frac{22}{7} or \: 3.14}} \\ \\ \huge{\sf\purple{ \implies \: x = 7}}$
