Solve using substitution
7x-9y=-9
x=-9

y=6

x=6.42

Step-by-step explanation:

7(-9)+9y=-9

-63+9y=-9

+63         +63

9y/9=54/9

y=6

7x-9(6)=-9

7x-54=-9

   +54   +54

7x/7=45/7

x=6.42

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
