using elimination method

2x + 3y = 6 -----(1)

-

x + 3y = 12-------(2)

———————

x = 12

substitute x as 12 into equation (1) or (2), let's choose equation (1)

2(12) + 3y = 6

24 + 3y = 6

collect like terms

3y = 6 - 24

3y = 18

divide both sides by 3 ( to make y the subject of formula )

3y = 18

— —

3 3

y = 6

therefore X = 12 and y = 6

Hope this helps eh

Good luck ✅.

The equation 4.05p+14.40=4.50(p+3)4.05p+14.40=4.50(p+3) represents the number pp of pounds of peanuts you need to make trail mix
AleksAgata [21]
4.05p + 14.40 = 4.5(p + 3)
4.05p + 14.40 = 4.5p + 13.5
14.40 - 13.5 = 4.5p - 4.05p
0.90 = 0.45p
0.90 / 0.45 = p
2 = p

Answer:

21 pairs of socks

Step-by-step explanation:

We can find out how much money Chang has to spend on socks by subtracting the price of sneakers from his total money to spend by solving 160 - 95. From that, we get our answer of $65 that Chang has to spend on socks. We can divide 65 by 3 to see how many pairs of socks he can buy and we get our answer of 21 pairs of socks.

(sorry if it's confusing but I hope it helped anyway)
