Answer:
step two
explanation:
the first 17.8 (-17.8) he was supposed to use was negative but the 17.8 (17.8) he used was not
3 feet is equal to one yard
3 feet is equal to 36 inches
J = jeans
T = t-shirts
You: 5j + 10t = 140
Friend: 3j + 5t = 79
To use elimination in this problem, multiply the second equation by -2 so that 10t and 5t can cancel out:
5j + 10t = 140
-6j - 10t = -158
We are left with -j = -18 or j = 18
Substitute 18 into any equation. I'll use the first equation:
5(18) + 10t = 140
90 + 10t = 140
10t = 50
t = 5
