-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49
y - 7x = 49 can be put into slope-intercept form by adding 7x to both sides. This gives you y = 7x + 49. This means that the slope of the line is 7, and the y-intercept is 49. So, plot the point (0,49). After that, for every time x increases by 1, y increases by 7. So, plot the point (1,56). Draw a straight line between (0,49) and (1,56) and draw arrow heads on both ends of the line to indicate that it continues infinitely.
7x7=49
-x + y = -7. There is nothing more that can be done with just one equation and two unknowns.

-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49
45+4 = 49 49/7=7 7*7=49-4=45 so x=7

49/4 or 12.25
Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.
8x - 7y = 7 (A)7x + 8y = 8 (B)7*(A): 56x - 49y = 498*(B): 56x + 64y = 648*(B)-7*(A): (64+49)*y = 64-49=> 113y = 15=> y = 15/113
If you mean: 7x = 49 then the value of x is 7
y - 7x = 49 can be put into slope-intercept form by adding 7x to both sides. This gives you y = 7x + 49. This means that the slope of the line is 7, and the y-intercept is 49. So, plot the point (0,49). After that, for every time x increases by 1, y increases by 7. So, plot the point (1,56). Draw a straight line between (0,49) and (1,56) and draw arrow heads on both ends of the line to indicate that it continues infinitely.
