8x + 2 y = 4
16x - y = 18
1 answer:
Solution to the system of linear equations is (5/3, -14/3)
Step-by-step explanation:
- Step 1: The system of linear equations are
8x + 2y = 4 ------ (1)
16x - y = 18 ------ (2)
- Step 2: Multiply eq(2) by 2 to make coefficients of y equal
8x + 2y = 4
16x - 2y = 36
- Step 3: Add the two equations
⇒ 24x = 40
⇒ x = 40/24 = 5/3
- Step 4: Find the value of y
⇒ 8 × 5/3 + 2y = 4
⇒ 40/3 + 2y = 4
⇒ 2y = 4 - 40/3 = -28/3
⇒ y = -14/3
