To eliminate the terms and solve for y in the fewest steps, by which constants should the equations be multiplied by before adding the equations together? First equation: 9x + 3y = -18

Second equation: 8x + 7y = 10

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

none.

step-by-step explanation:

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

m1=5,m2=0

he answer is x=1x3 because x=1 to x=3
