Hi there,
No, it isn't
5x - 3 = 12
5x = 12 + 3
5x =15
Hence, X = 3
3 is the solution
Hope this helps :)
Answer:
63
Step-by-step explanation:
let the two numbers be x,y (x>y)
Then x+y = 16 and x-y = 2
We know that (x+y)^2 - (x-y)^2 = 4xy
So 4xy = 16^2 - 2^2 => 4xy = (16+2)(16–2)
So xy = 18×14/4 = 63
Product of the numbers = 63

Answer:
D.five more than the quotient of 6 and a number,
Step-by-step explanation:
To evaluate the the phrase written as :
6/r+5
Here, there is no bracket to make any distinction, hence using the BODMAS mode of evaluation, we deal with the division first before the sum. Hence we interpr te the equation as :
6 / r = quotient ; then, 5 is added to the quotient obtained from the divison of 6 by r.
3)
26 + ( 3x + 1 ) = 180
27 + 3x = 180
3x = 180 - 27
3x = 153
x = 153/3
x = 51

4)
( 4x + 1 ) + ( 3x + 4 ) = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/5
x = 25
