Answer:
43
Step-by-step explanation:
3x + 10 = 5x - 12
10 = 2x - 12
22 = 2x
x = 11
check:
33 + 10 = 55 - 12
43 = 43
correct
x = 11 so bring this into 3x + 10
we get 43
Answer:
Each shirt costs 12 dollars.
Each pair of pants cost 40 dollars.
Step-by-step explanation:
<u>Let x represent the shirts </u>
<u>Let y represent the pair of jeans</u>
10x + 4y = $280
12x + 5y = $344
<u>Use elimination method to eliminate y</u>
• Multiply the entire first equation by 5.
• Multiply the second entire equation by -4.
5(10x +4y = $280)
-4(12x + 5y = $344)
50x + 20y = 1400
-48x -20y = -1376
2x = 24
x = 12
Each shirt costs 12 dollars.
<u>Solve for how much each pair of jeans costs.</u>
10(12) + 4y = 280
120 + 4y = 280
4y = 160
y = 40
