Answer:
11.4
Step-by-step explanation:
14.12= 1/2(3.6x-12.8)
14.12=1.8x-6.4
20.52=1.8x
x=11.4
Hope that helps :)
Lemme know if I need to explain more
x = 11.4
14.12 = ( 3.6x - 12.8 )
Rewrite so that the equation is entirely in decimals;
14.12 = 0.5( 3.6x - 12.8 )
Distribute;
14.12 = 1.8x - 6.4
Inverse operations;
+6.4 +6.4
20.52 = 1.8x
/1.8 /1.8
11.4 = x
35
x-18=y
y*-3=-51
y=17
x-18=17
17+18=x
x=35
