Answer

Number is 4

Work Step by Step

Let the number be $\Longrightarrow$ x Thus 5 added to 4 times the number = 4(x) + 5 = 4x + 5 Given: $\frac{4x + 5}{6}$ = $\frac{7}{2}$ Cross multiplying, 2(4x + 5) = 7(6) 8x + 10 = 42 8x + 10 - 10 = 42 - 10 ... (Subtracting 10 from both sides) 8x = 32 x = $\frac{32}{8}$ x = 4
