9 is the anser trust me i just took the test i hate computer scored test but that is the answer
Answer:
3x+75=180
3x=180-75
3x=105
x=105/3
x=35
Answer:
Step-by-step explanation:
So y+x=2
x-y=4
one way is subsituteion where yousubisutte one of the number for another exg
x-y=4
add y to both sides
x=y+4
subsitute y+4 for x in x+y=2
y+4+y=2
2y+4=2
subtract 4 from both sides
2y=-2
divide both sides by 2
y=-1
subsiutte
x+y=2
x-1=2
x=3
or elimination
x+y=2
x-y=4
add the two equations and cancel the y terms
x+x+y-y=2+4
2x=6
divide both sides by 2
x==3
subsitute
x+y=2
3+y=2
y=-1
so x=3
y=-1
Answer:3x
Step-by-step explanation:
If 2x+y=2y−x, then the value of y in terms of x can be
3x
