Answer:
see explanation
Explanation:
let t be the cost of 1 t- shirt and s be the cost of 1 pair of shoes , then
4t + 3s = 325 → (1)
2t + 2s = 194 → (2)
(b) Solving by elimination
Multiplying (2) by - 2 and adding to (1) will eliminate t
- 4t - 4s = - 388 → (3)
Add (1) and (3) term by term to eliminate t
0 - s = - 63
- s = - 63 ( multiply both sides by - 1 )
s = 63
Substitute s = 63 into either of the 2 equations and solve for t
Substituting into (2)
2t + 2(63) = 194
2t + 126 = 194 ( subtract 126 from both sides )
2t = 68 ( divide both sides by 2 )
t = 34
Cost of pair of shoes = AED 63 and cost of t- shirt = AED 34
