-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)

First answer: 6 and 8
6 + 8 = 14
6 * 8 = 48
Second answer: 14 in the middle, 350 on top.
39 - 25 = 14
25 * 14 = 350
Just explaining instead of using x for the variable I'm going to use t just so u don't get mixed up with the multiplication symbol and the variable.But on your paper you must use d or else you won't receive full credit.
15tx4>50
On this I can't add a greater than and equal to symbol, but that greater than must have a line under it to represent greater than and equal to. Hope this helps
