Question

Use the substitution method to solve the system of equations. Choose the correct ordered pair.

2x + 3y = 29
x = 4

A. (3, 2)
B. (4, 11)
C. (4, 7)
D. (7, 4)

Answer 1

2*4+3y=29
3y=21
y=7
x=4 choice c

Answer 2

solution of the given system of equation is (4,7)

C is the correct option.

Explanation:

The given system of equations is

`2x+3y=29...(i)\\\\x=4...(ii)`

Substituting the value of x from (ii) in equation (i)

`2\cdot4+3y=29\\\\8+3y=29\\\\3y=21\\\\y=7`

Therefore, the solution of the given system of equation is (4,7)

C is the correct option.
