Consider the following pair of equations:

y = 3x + 3
y = x − 1

explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

Hence y=3x+3 & y= x-1
so 3x+3 = x-1
3x-x = -1-3
2x= -4
x= -2
by substitute in any equation to get the value of y
i'll sub. in the second
y= x-1
y=-2-1
y=-3
so the answer is (-2,-3)

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
