Answer:
this is a simultanious equation and u need one more equation to do it
Step-by-step explanation:
there are many answers if u dont have the second equation.
You can just substitute a number in x then find y
eg.
x= 12/7 , y =0.5
Answer:
1. 7 x - 4 y = 10. 7x−4y=10. Add 4y to both sides. Add 4y to both sides.
2. 7x=10+4y. 7x=10+4y. The equation is in standard form. The equation is in standard form.
3. 7x=4y+10. 7x=4y+10. Divide both sides by 7. Divide both sides by 7.
4. \frac{7x}{7}=\frac{4y+10}{7} 77x=74y+10 Dividing by 7 undoes the multiplication by 7.
