Answer: y = 4x + 20
Step-by-step explanation:
4x - y = -20
=> -y = -4x - 20
=> y = 4x + 20
Answer:
1. x + y = 25
2. x - y = 7
3. x = 16, y = 9
Step-by-step explanation:
(x + y = 25) + (x - y = 7)
2x (the y cancels) = 32
32/2 = 16, x = 16
substitute x in either equation
16 + y = 25
y = 9
Answer:
The correct option is:
The student should have switched the direction of the inequality sign to get –5> x for a final answer
Step-by-step explanation:
The students has made a mistake in the 3rd step.
We know that when we multiply or divide any negative number on both sides of the inequality, the sign of inequality reverse its direction.
In step 3 the student divided 25 by -5 but did not switch direction of the inequality sign.
Therefore the correct option is: The student should have switched the direction of the inequality sign to get –5> x for a final answer....
