Answer:
1.) 2x-y=-7 --> y=2x + 7
2.) 5x+3y=12 --> y= -5/3x + 4
3.) x-y=1 --> y= x- 1
4.) x-3y=-15 --> y=1/3x + 5
5.) 8x-10y=20 --> y=4/5x - 2
6.) 14x+6y=36 --> y=-7/3x+6
Step-by-step explanation:
Hope this helped.
-x + -x-1 + -x-2 = -204
-3x=-201
x=-67
-67-68-69=-204

Step-by-step explanation:
Cameron task: 3/7 × 2/9
What he did:
• Simplify 3/7 to 1/7
• mulitiplied the fractions 1/7 and 2/9
Cameron's error was:
• The "simplification":
To simplify a fraction is to reduce to the lowest possible multiple. Illustration:
Simplify 16/100
= 2/25
But in the case of 3/7, the answer is 3/7.
What Cameron would have done:
1. 3/7 = 2/7 + 1/7
3/7 × 2/9 = (2/7 × 2/9) + (1/7 × 2/9)
= 4/63 + 2/63
= 6/63
2. since he simplified 3/7 to 1/7
1/7 = 3/7 × 1/3
Therefore,
3/7 × 2/9 = 1/7 × (2/9 × 3)
= 1/7 × 6/9
= 6/63
