Answer:
Step-by-step explanation:
We can combine the -7x and the -2x and the left side to get -9x and the 23 and 13 on the right side to get 36.
This gives us
-9x + 12 = 36
Subtacting 12 from both sides gives us
-9x = 24
dividing by -9 gives us
x = - 8/3
Answer:
5< 10x -3
add like terms first
make sure X's are on one side and numbers on the other
30=(10*3*x)/2
*2 *2
60=10*3*x
60=30x
60/30=30x/30
2=x
