Answer 2

Since 2x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2x from both sides.
3x+2y=4
−y=−2x+5
Divide each term in the equation by −1.

3x+2y=4
y=2x−5
Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is 2x−5.
3x+2(2x−5)=4
y=2x−5
Simplify each term.

3x+4x−10=4
y=2x−5
Add 3x and 4x to get 7x.
7x−10=4
y=2x−5
Since −10 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 10 to both sides.
7x=10+4
y=2x−5
Add 10 and 4 to get 14.
7x=14
y=2x−5
Divide each term in the equation by 7.

x=2
y=2x−5
Replace all occurrences of x with the solution found by solving the last equation for x. In this case, the value substituted is 2.
x=2
y=2(2)−5
Multiply 2 by 2 to get 4.
x=2
y=4−5
Subtract 5 from 4 to get −1.
x=2
y=−1
The solution to the system of equations can be represented as a point.
(2,−1)

Answer 3

therefore it has on solution

Answer 4

8x + 13y = 2
y = x - 2
Solve the system of equations

Answer 5

hold on

Answer 6

(4/3, -2/3)

(4/21, -38/21)

No solution

Answer 7

\(\large\color{black}{ \displaystyle 3x + 2y = 4 }\)
\(\large\color{black}{ \displaystyle 2x - y = 5 }\)

\(\large\color{black}{ \displaystyle 2x - y = 5~~~~\Rightarrow~~~~y=2x-5}\)

\(\large\color{black}{ \displaystyle 3x + 2y = 4~~~~\Rightarrow~~~~3x + 2(2x-5) = 4 }\)
