Answer:
cost of a pair of jeans=370rupees
cost of t-shirt=320rupees
Step-by-step explanation:
Let,
cost of 1 Jean be X
cost of one t shirt be y
4x+3y=1350 ------- 1eqn
2x=y+50
2x-y=50 -------- 2 eqn
Add eqn 1 and 2...
2 eqn *3 = 6x - 3y =150
1 eqn = 4x +3y =1350
__________________________
10x+0=1850
__________________________
x=1850/10
x=185....
Substitire x in eqn 2
2(185)-y=50
y=370-50
y=320
