You substitute the y from the second eqaution to the y in the first equation
You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.

Answer: The price of 1 football = $ 7 and price of 1 basket ball= $10
Step-by-step explanation:
Let x = price of 1 football.
y = price of 1 basketball.

Multiply 3 to (ii) , we get

Eliminate (i) from (iii)

Put this in (ii), we get

Hence, the price of 1 football = $ 7 and price of 1 basket ball= $10
30 * x = 245
lets divide 30 and 245, 245 / 30 = 8.167
8.167 x 30 = 245
hope it helped
