Question

3x + 4y = 5 and 2x + 3y = 7
Find the solution to each system. Write your solution as an ordered pair

Answer 1

Answer:

( -13 , 11 )

Step-by-step explanation:

3x + 4y = 5

2x + 3y = 7

Eliminate x

-2 ( 3x + 4y = 5 )

3 ( 2x + 3y = 7 )

-6x - 8y = -10

6x + 9y = 21

Simplify

y = 11

Substitute y in any equation to get x

2x + 3(11) = 7

2x + 33 = 7

2x = -26

x = -13
