Use the system of equations to answer the questions. 2x + 3y = 3 y = 8 – 3x The value of y from the second equation is substituted back into the first equation. What is the resulting equation? What is the value of x? What is the value of y?

Verified Answer :

Answer:

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;

\(2x+3(8-3x) =3\)

Using distributive property on LHS, (i.e, \(a\cdot(b+c) = a\cdot b+ a\cdot c\) )

\(2x+3\cdot 8+ 3 \cdot (-3x) =3\) or

2x+24-9x =3

Combine like terms;

\(-7x+24 =3\)

Subtract 24 from both the sides,

\(-7x+24-24=3-24\)

Simplify:

-7x =-21

Divide by -7 to both sides of an equation;

\(\frac{-7x}{-7} = \frac{-21}{-7}\)

Simplify:

x =3

Substitute the value of x =3 in equation [2] to solve for y;

\(y=8-3(3) =8 -9 =-1\)

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

The value of x =3 and that of y = -1.

Given the system of equations:

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;

\(2x+3(8-3x)=3\)

Using distributive property on LHS,

What is the distributive property?

\(a(b+c)=ab+ac\)

\(2x+24-9x =3\)

Combine like terms;

\(-7x+21=0\)

Subtract 24 from both the sides,

Simplify

-7x =-21

Divide by -7 to both sides of an equation

x =3

Substitute the value of x =3 in equation [2] to solve for y;

y=8-3(3)

y=8-9

y=-1

Hence, the answer to this question is:

\(2x+3(8-3x)=3\)

The resulting equation is: \(2x+3(8-3x)=3\)

And the value of x =3 and that of y = -1.
