The answer is B
Explanation-the two line intersects at point -1,7
2x+9= 35
Move 9 to the other side
positive +9 changes to negative -9
2x+9-9= 35-9
2x= 26
Divide by 2 for 2x and 26
2x/2= 26/2
x= 13
Check answer by using substitution method
2x+9= 35
2(13)+9= 35
26+9= 35
35= 35
Answer : x= 13 ( first choice)
3x=12
You want to find x so isolate x to find what the value is.
So divide the whole equation by 3 to make x by itself.
(3x)/3=12/3
x=12/3
x=4
Check your answer:
3(4)=12
Yes, 3 times 4 is 12.
