What’s 8X +15 equals 63

6

Step-by-step explanation:

You should do the equation on reverse:

63-15 = 48

48 divided by 8 = 6

X=6

Step-by-step explanation:

Minus 15 from itself and 63. Then you take that answer and divide that from 8. Then x should equal 6.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
