Answer:
No solutions
Step-by-step explanation:
4(2x-3)=2(4x-6)

Same components are present on both sides of equal sign, therefore NO SOLUTIONS are possible.
Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
The formula for calculating the equation of line in point - slope form is given as :
where m is the slope
Given from the question :
m = - 4
= 2
= 6
Substituting into the formula , we have :




Therefore :
(a) the equation of the line in point - slope form is 
(b) to write it in slope - intercept form , we will make y the subject of the formula , which will give : 
(c) the equation of line in standard form is ; 
Answer:
Step-by-step explanation:
16 x 28% = 4.48
16 x 72% = 11.52
16 x 172% = 27.52
16 x 128% = 20.48

I dont know for the second one, sorry-
Answer:

Step-by-step explanation:
x-7y = -49
i) move x to the right-hand side and change its sign
-7y = -49-x
ii) change the signs on both sides of the equation
7y = 49+x
iii) divide both sides of the equation by 7


iv) use the commutative property to reorder the terms
* commutative property: a+b = b+a

The answer is 9.63 x 10^12
