-3x + 7x = -12
You need to add like terms.
4x = -12
Then, you need to divide both side by 4.
x = -3
So the answer is:
A) x = -3
Answer:
The answer is A.) -3
Step-by-step explanation:
x ( -3 + 7) = -12 use distributive property to factor out the x. So
x (4) = -12 add the like terms inside parenthesis
¼ * 4x = -12 *
1
4
multiply both side by the reciprocal of 4
x = -3 final answer

Hello :
(2, 6) is a solution of y - x > -3 because : 6-2> -3 ..... 4 > -3
14-x=9
14=x+9
x=14-9
x=5
14+5=19
x+y=19
x-y=(-5)
Adding both equations,
We get,
x+y=19
x-y=(-5)
2x=14
x=7
x+y=19
7+y=19
y=12
