Question

8.3z=4.1z+10.5 math fufifu

Answer 1

first subtract 4.1z on both side and you get 4.2z=10.5 then divide 4.2 on both side and you get z=2.5

Answer 2

First drag the positive 4.1z to the other side so you can subtract it from 8.3z
8.3z-4.1z = 10.5
8.3z-4.1z= 4.2z
4.2z=10.5
z=
`(10.5)/(4.2)` (10.5 ÷ 4.2)
z=2.5 or
`2 (1)/(2)`
