Step-by-step explanation:
123/6 x 7[(654 + 2) x (12/3)].....do whats in parenthesis first
123/6 x 7[656 x 4] ......do whats in brackets
123/6 x 7(2624) ....do multiplication/division from left to right, whichever comes first
20.5 x 18,368 =
376544 <===
Answer:
1. x = 2
y = 1
2. x = 3 or 6 (Mistake or typo in problem)
3. y = 13
4. x = 7
y = 15
5. x = 4
Step-by-step explanation:
1. 6x - 3 = x + 7, 5x = 10, x = 2
3y + 2 = y + 4, 2y = 2, y = 1
2. There is most likely a typo. Either 8x = 24 and x = 3 or 2x + 10 = 3x + 4 and x = 6
3. 5y -3 = 2y + 36, 3y = 39, y = 13
4. 8y + 11 + 3y + 4 = 180, 11y + 15 = 180, 11y = 165, y = 15
7x = 3y + 4 = 49, x = 7
5. 7x - 10 = 4x + 2, 3x = 12, x = 4
36 85
X 100
3600 = 85x
3600 divided by 85 =42.3529...
Y=6x-11
-2x-3y=-7
Take "6x-11" and insert it where it says 3y. Now you have:
-2x-3(6x-11)=-7
Use distributive property (-3 × 6x) ( -3 × -11). Now you have:
-2x-18x+33=-7
Combine like terms. (-2x + -18x). Now you have:
-20x+33=-7
Subtract 33 from both sides (33-33 and -7-33). Now you have:
-20x=-40
Divide -20 from both sides (-20x/20 and -40/-20). Now you have:
Answer: x= 2
