solve the $3$ control system cource problem please

Determine the transfer function of this system by reducing ts shown black diagram

Selurat an

$=\frac{C(2)}{H_{(2)}}=G_1{G}_2+G_3-1$

$=\frac{C(x)}{R(2)}=G_1{G}_2-G_2+G_1-1$

$\frac{C(2)}{H(2)}=\frac{G_1{G}_1+G_1}{1+G_1{G}_2+G_2}$

$(1)\frac{G(2)}{n(x)}=\frac{G_1{G}_1+G_2}{1-G_1{G}_2-G_2}$

$\frac{C(0)}{H(a)}=\frac{G_1{G}_1}{1+G_1+G_3{G}_2{H}_1}$

Nore of these

${?}^2\frac{C(p)}{H(a)}=\frac{G_1{G}_1}{1+G_1+G_2{H}_1}$

$+\frac{C(0)}{H(0)}=\frac{G_1{G}_1}{1+G_1+G_3{Z}_1}$

$\frac{G(0)}{H(x)}=\frac{G_i}{1+G_i+G_1{G}_2{H}_1}$
