Which equation is equivalent to the equation 3x - 12 = 24? A) 15x - 60 = 120
B) 3x = 12
C) 3x = 36
D) x - 4 = 8
E) 12x - 12 = 24

C

Step-by-step explanation:

To simplify the equation, all you need to do is add 12 to both sides to cancel out the -12.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

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
