Answer:
---- equation 1
---- equation 2
A microscope costs S51 and a dissection kit costs S17
Step-by-step explanation:
Given
Represent microscope with M and Dissection kits with D
Cost:
Required
Represent as an equation:
To do this, we represent the equation in terms of cost and quantity
In terms of cost, we have:
---- equation 1
and
---- equation 2
Substitute 3D for M in equation 1
Divide both sides by 134
Substitute 17 for D in
Hence:
<em>A microscope costs S51 and a dissection kit costs S17</em>
