Use elimination
Subtract both
4y = 4, y = 1
3x + 2 = 14
3x = 12, x = 4
Final answer: x = 4, y = 1

Answer:

(4, 1 )

Step-by-step explanation:

Given the 2 equations

3x + 2y = 14 → (1)

3x - 2y = 10 → (2)

Adding the 2 equations term by term, eliminates y , that is

6x = 24 ( divide both sides by 6 )

x = 4

Substitute x = 4 into either of the 2 equations and solve for y

Substituting into (1)

3(4) + 2y = 14

12 + 2y = 14 ( subtract 12 from both sides )

2y = 2 ( divide both sides by 2 )

y = 1

Solution is (4, 1 )
