(b) By using your answer in part (a) andgiyen that 2CD=3AB , find the value ofy. 2y=3x-1 x+y=30 y=(3x)/(2)-(2) x+(3x)/(2)=303x^(2) 2x+3x=60 5x=60 x=12 y=(3(12))/(2) 18cm Answer y= qquad =18% 4 Solve the following simultaneous equations. 2y=x-4"-(1) " 2y=x-4 2x=3-y ],[2y=x-4-(1)],[y=3-2x-(2)],[y=3-2(2)],[2(3-2x)=x-4],[=-111],[6-4x=x-44],[10=5x],[5x=10],[x=2" 11 " Answer x=dots dots dots,y=dots dots dots dots[3]

1. Given the equations: From the provided solution: Substituting the value of into the first equation:\(y = \frac{3(12)}{2}\) Thus, cm.2. Given the equations: From the provided solution:\(2(3 - 2x) = x - 4\) Substituting the value of into the second equation:\(y = 3 - 2(2)\) Thus, and .
