Answer:
c=-5
Step-by-step explanation:
2c-3=12-2c+7c
2c-3=12+5c
2c-5c-3=12
-3c-3=12
-3c=12+3
-3c=15
c=15/-3
c=-5
Given:
The width of a kitchen is 4.2 metres.
Kitchen cupboard widths are 60 cm.
To find:
The number of kitchen cupboard that will fit in 4.2 metres.
Solution:
Let x be the number of kitchen cupboard that will fit in 4.2 metres.
Width of 1 cupboard = 60 cm
Width of x cupboards = 60x cm
We know that, 1 m = 100 cm.
Width of a kitchen = 4.2 metres
= 4.2×100 cm
= 420 cm
Now, the width of the x cupboards is equal to width of the kitchen.



Therefore, the number of kitchen cupboard that will fit in 4.2 metres is 7.
