Answer:
24c
Step-by-step explanation:
Difference= big value - small value
When minus is put side by side, it becomes a plus.
17c-(-7c)=17c+7c=24c
Answer:
The two lines intersect (in other words, they have a common meeting points)
Step-by-step explanation:
Thinking process:
A linear equation takes the form of 
where , m = gradient
c = y-intercept (point where the line cuts the y-axis)\
Suppose we have these two linear equations: 
We can find the point of intersection by solving the two equations simultaneously like this:
sub y = 2x + 4 into equation (2) gives:
2(2x+4) = -6x -1
solving yields
- 0.9
Substituting x= -0.9 into equation 1 yields:

y = 2.2
In terms of the Cartesian coordinates (x, y) the point of intersection will be (-0.9, 2.2)
Hence, the point of intersection is a solution of two linear equations.
ANSWER: 11.08
EXPLANATION: Add a zero after the 9 to make the number 29.90. Then subtract normally.
the problem would be set up as 6+(7*x)=41
first u take off the number 6 by subtracting it from itself to cancel it out then u do the same to the number 41
7x =41 now u need to cancel out the number 7 attatched to the x so u divikde it by itself and then do the same to the other side so 41 divided by 7 =5.9
so x =5.9
