Answer:
x=1638831.492383738758729e+23f+0
Step-by-step explanation:
(1123)(x)=983298f+(220.22)(38)
Step 1: Divide both sides by 8.954302432552374e+23.
8.954302432552374e+23x
8.954302432552374e+23
=
983298f+1842545.52
8.954302432552374e+23
x=
163883
1.492383738758729e+23
f+0
A number that's bigger than 4.3 is the answer :)
