Answer:

x = -80

Explanation:


(1)/(2)(x-10)=(3)/(4)(x+20)\\\\\\(1)/(2)x-(1)/(2)*10=(3)/(4)x+(3)/(4)*20\\\\\\(1)/(2)x-5=(3)/(4)x+3*5\\\\\\(1)/(2)x-5=(3)/(4)x+15\\\\\\(1)/(2)x-5-15=(3)/(4)x\\\\\\(1)/(2)x-20=(3)/(4)x\\\\\\-20=(3)/(4)x-(1)/(2)x\\\\\\-20=(3)/(4)x-(1*2)/(2*2)x\\\\\\-20=(3)/(4)x-(2)/(4)x\\\\\\-20=(1)/(4)x\\\\\\-20*4=x\\\\\\x = -80
