Heya☺
4/10 z - 30/15 z = 7/5 - 9
2/5z - 2z = (7-45) ÷5
-8/5 z = -38/5
z = 38/5 × 5/8
z = 38/8
z = 4. 75
✌✌ Hope this helps!

Hi...✌
0.4z-3/1.5z+9 = 7/5
0.4z - 2z = (7/5) -9
-1.6z = (7-45)/5
-1.6z = -38/5
z = 38×/(5×1.6)
z = 38/8
z = 4.75
0.4z-3/1.5z+9 = 7/5
0.4z - 2z = (7/5) -9
-1.6z = (7-45)/5
-1.6z = -38/5
z = 38×/(5×1.6)
z = 38/8
z = 4.75
There's a mistake
It will be 5 instead of 9
Thank you
No problem
:)
