C) =23X -51= 7X +77
23X-7X =77 +51
16X = 128
X = 128/ 16
X=8
D) 5.( 3X- 16) = 240 -5X
15X -80 =240 -5X
15X +5X =240
20X = 240/ 20 =12
E) X/4 -29 =37
X-116 =148
X =148 + 116
X =264
23X-7X =77 +51
16X = 128
X = 128/ 16
X=8
D) 5.( 3X- 16) = 240 -5X
15X -80 =240 -5X
15X +5X =240
20X = 240/ 20 =12
E) X/4 -29 =37
X-116 =148
X =148 + 116
X =264
