Therefore Natalie bought 3 water melons and 10 strawberries
Step-by-step explanation:
Step 1
let watermelons be represented by w
and strawberries be represented by s
Step 2
5w +3s = $45eqn 1
w+s=13eqn 2
Making w subject of formulae and substituting in equation 2
w= 13-s
5(13-s) + 3s=45
65-5s+3s =45
65-45=5s-3s
20=2s
s=20/2=10
substituting s=10 in equation 2
w +10=13
w= 13-10
w=3
Therefore Natalie bought 3 water melons and 10 strawberries
