Question

Which ordered pair is the solution to the system of equations?

Y=2x – 15
4x + 3y = -5
A (0,6)
B (7, – 11)
C (4, – 7)
D (5, — 5)

Answer 1

Explanation:

y = 2x - 15

4x + 3y = -5

4x + 3(2x - 15) = -5

4x + 6x - 45 = -5

10x = 40

x = 40/10

x = 4

y = 2x - 15

y = 2(4) - 15

y = 8 - 15

y = -7

Solution = (4,-7)

Option → C
