What is the value of y in the solution to the following system of equations?
ddd [48]
2x+ y = -4       5x + 3y = -6
y= -4 -2x    

substitute y=-4-2x into 5x+3y=-6
5x + 3(-4-2x) = -6
5x -12 -6x =-6
-x=6
x=-6

sub x=-6 into 2x+y=-4
-12 + y = -4
y=8

x=-6 and y=8

18(26) using distributive property and simplify
podryga [215]

Using distributive property and simplifying 18(26) we get 468

Step-by-step explanation:

We need to use distributive property and simplify: 18(26)

The distributive property stays that: a(b+c)=ab+ac

We can write 26 as 20+6

18(26)= 18(20+6)

Solving 18(20+6) using distributive property

18(20+6) =18*20+18*6

              = 360+108

              = 468

So, using distributive property and simplifying 18(26) we get 468
