Answer:
I think its D)
Step-by-step explanation:
7x−3y+2=0
Add -7x to both sides.
7x−3y+2+−7x=0+−7x
−3y+2=−7x
Add -2 to both sides.
−3y+2+−2=−7x+−2
−3y=−7x−2
Divide both sides by -3.
−3y
/−3 = −7x−2
/−3
which equals d)
I also use this app to convert equations to slope-intercept and it showed me this
Answer:
x = 5
Step-by-step explanation:
A by B is simply 
3 by x + 1 is
5 by 2x is
So, the equality is ;
=
Cross multiply and solve the inequality;
3(2x) = 5(x + 1)
6x = 5x + 5
6x -5x = 5
x = 5
