I believe that would be -4.50 for problems like this you subtract then add the negative sign in front
i'm surprised you are in high school i did this in 6th grade
(x+y=31)2
2x-y=11
2x+2y=62
- 2x -y=11
3y=51
y=17
x+17=31
x=14
y-x=3
Answer:
x =4
Step-by-step explanation:
2/3(x-7)= -2
Multiply each side by 3/2 to clear the fractions
