Answer:
y=15
x=43
(any variable can be used, I used x and y to make it easier to show)
Step-by-step explanation:
x+y=58
x-y=28
get x by its self
x=58-y
then subsitute into the other equation
(58-y)-y=28
58-2y=28
-2y=-30
y=15
sub. again
x+15=58
x=43
Answer:
x= -3-sqr30/7
Step-by-step explanation:
Answer:
First, assign a value to x.<em> x</em> will be 2 in this case.
Next, multiply x by itself, because that is what exponent 2, or squared, means. 2 x 2 = 4
Now, multiply 4 by 7. 4 x 7 = 28
Next, find the value of <em>9x</em>.
The value of 9x will be 9 times a number, x, also known as 2 in this scenario. 9 x 2 = 18
Then, subtract 28 from 18. 28 - 18 = 10
Lastly, subtract 10. 10 - 10 = 0
Therefore,
The answer is 0. <em>Product may vary depending on value assigned to x.</em>
