Best ResponseYou've already chosen the best response.1Anytime you see paretheses we need to see if we can distribute \[\huge~\rm~2/3(x2)=4x\] can we?

Best ResponseYou've already chosen the best response.1Subtract 4x from both sides. \[\huge~\rm~2 /3 x4x+ −4 /3 =4x4x\] \[\huge~\rm~10/34/3=0\] Add 4/3 to both sides. \[\huge~\rm~10/3+4/3 −4 /3 =0+4/3\] \[\huge~\rm~−10/ 3 x= 4/ 3\] multiply by the reciprocal (flip fraction to 3/10) \[\rm~( 3 −10 )*( −10 /3 x)=( 3/ −10 )*( 4 /3 )\]

Best ResponseYou've already chosen the best response.0i dunno whether is correct or not, below is my solution: 2/3 = 4x / (x2) 2(x2) = 12x 2x  4 = 12 x 4 = 12x2x 4 = 10x x= 4/10 x = 2/5

Best ResponseYou've already chosen the best response.2\(\sf\Large\frac{2}{3}(x2)=4x\) Multiply by the reciprocal of \(\sf\Large \frac{2}{3}\) on both sides. The reciprocal of \(\sf\Large \frac{a}{b}\) is \(\sf\Large \frac{b}{a}\)
