Answer:
x = 5
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + [tex]\frac{5}{2}[/tex] ) = [tex]\frac{15}{4}[/tex]
Multiply both sides by 4 to clear the fractions
2(x + [tex]\frac{5}{2}[/tex] ) = 15 ← distribute parenthesis on left side
2x + 5 = 15 ( subtract 5 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Answer:
x = 5
Step-by-step explanation:
i solved x using trial and error
1/2 (x+ 5/2)= 15/4
so i tried with 2
1/2 (2 + 5/2)= 9/4
which is too less, so i tried with 7
1/2 (7+ 5/2)= 19/4
which is too big, so i tried with 6
1/2 (6+ 5/2)= 17/4
which is nearly there and i tried with 5
1/2 (5+ 5/2)= 15/4
and it came exactly
