2x - 4y = -2
2x + 3y = -16
------------------subtract
-7y = 14
y = 14/-7
y = -2
2x - 4y = -2
2x - 4(-2) = -2
2x + 8 = -2
2x = -2 -8
2x = -10
x = -10/2
x = -5
answer x = -2 and y = -5
check:
2(-5)- 4(-2) = -2
-10 +8 = -2
-2 = -2.....true
2x + 3y = -16
2(-5)+3(-2) = -16
-10 + (-6) = -16
-16 = -16...true
Hello!
-7 + 9 = x + 1
2 = x + 1
2 - 1 = x
1 = x
I hope this helps you! Have a lovely day!

Answer:
9x^3-74x+28
X
Step-by-step explanation:
USED PHOTOMATH BTW. DUNNO IF ITS RIGHT OR WRONG.
Given:
To find:
The values of x.
Solution:
We have,
(Distributive property)
(Combining like terms)
Add 28 on both sides.
Subtract 10x from both sides.
Divide both sides by 14.
Therefore, the values of x are all real numbers less than 2, i.e., x<2 .
Are you factoring ?
