The value of x in this system of equations is 1.3x + y = 9y = –4x + 10substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9–x + 10 = 9–x = –1x = 1what is the value of y?

3x + y = 9

y = –4x + 10

First we will substitute y= -4x+10 in the first equation in place of 'y'

3x + (-4x+10)= 9

⇒3x -4x +10 = 9

⇒ -1x +10 =9

⇒ -1x = -1

⇒ x = -1/-1 = 1

⇒ x= 1

Now, for finding the value of y , we will plug x=1 into the second equation.

y= -4x +10

y= -4(1) +10

y= -4 +10

y= 6

So, the value of y is 6 .

step-by-step explanation:

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
