Answer:
x = 1/(a-b)
Step-by-step explanation:
The given equation is ax = bx + 1
Collecting like terms:
ax - bx = 1
Factorizing x out of the equation:
x(a - b) = 1
Dividing both sides by (a - b):
Therefore, x is related to the difference of a and be by the equation
x = 1/(a-b) where a - b is the difference of a and b
Step-by-step explanation:
multiply 5x+2y=19 by 3 youll get 15x+6y=57
eliminate y
7x-6y=9
<u>15x+6y=57</u><u> </u> +
22x=66
x=3
substitute x to 5x+2y=19
15+2y=19
2y=4
y=2
Answer:The number is -1.5
Step-by-step explanation:
The answer is -1.5 because if you can't use a number less than -1.5 or greater than -1.5 than the answer should be -1.5.
21/50 is 42 percent of the students. You will have to find 42 percent of 350 to know. 42 percent of 350 is 147.
The second answer is right
Answer:
Step-by-step explanation:
4x - 2y = 6
-2y = -4x + 6
y = -4x/-2 + 6/-2
y = 2x - 3
