Answer 1

Answer:

t-shirts = 8, hats= 15

Step-by-step explanation:

let the no of of t-shirt be x

and the no of hats be y

$x+y= 23-----------1$

$8x+10y= 154---------2$

solving equations 1 and 2 simultaneously we have

multiplying equation 1 by 8 and subtracting from 2 we have

$8x+8y=184-------------4\\-8x+10y=154------------2$  

$=0x-2y=30$

$y=\frac{-30}{2} \\y=-15$

y= 15

substituting y= 15 in equation 1 to find x we have

$x+15=23\\x=23-15\\x= 8$

x=8
