2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)
Answer:
When you multiply two integers with the same signs, the result is always positive.
Step-by-step explanation:
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative.
D. X = -7
Step 1: Subtract 8 from both sides.
x + 8 - 8 = 1 - 8
Answer:
x = -7
Y +5=2y+1 has the same result.
Answer: D
Step-by-step explanation:
All would add up to 241 instead of 2.41 because you are not using decimals for the constants (Example: 25q not .25q)
