Answer:
x=3 y=-1
Step-by-step explanation:
To get the value of x you need to put in the second equation which is y=8-3x as the y value for the first equation which is 2x+3y=3 making it
2x+3(8-3x)=3
2x+24-9x =3
24-7x =3
-7x=-21
Multiplying both sides by -7
x= 3
After getting an x value you substitute it in the equation in order to find your y value which is
2x+3y=3
2(3)+3y=3
3y=-3
Multiplying both sides by 3
y= -3
3
y=-1
Answer:
First Box: B or 2x+3(8-3x)=3
Second Box: C or 3
Third Box: A or -1
Correct For Edg 2020
Why?
Given the system of equation:
2x+3y=3 ......[1]
y=8-3x ......[2]
as per the given condition;
Substitute the value of y from the equation [2] into the [1] equation;
Using distributive property on LHS, (i.e, )
or
2x+24-9x =3
Combine like terms;
Subtract 24 from both the sides,
Simplify:
-7x =-21
Divide by -7 to both sides of an equation;
Simplify:
x =3
Substitute the value of x =3 in equation [2] to solve for y;
Hence, the answer for this question is:
The resulting equation is: 2x+3(8-3x)=3
And the value of x =3 and that of y = -1
