Mathematics: What is the solution of the system? use the elimination method. -4x + y = -6 18x – 2y = 14 the only solution is (0, - 3/2) the only solution is (0,– 6). there is an infinite number of solutions. there is no solution.

The only solution is (0.2,-5.2)

Step-by-step explanation:

we have

-4x + y=-6 ----> equation A

18x-2y=14 ----> equation B

Solve the system by elimination

Multiply the equation A by 2 both sides

2(-4x + y)=2(-6)

-8x + 2y=-12 -----> equation C

Adds equation C and equation B

$-8x + 2y=-12\\18x-2y=14\\-------\\-8x+18x=-12+14\\10x=2\\x=0.2$

Find the value of y

substitute the value of x in any of the equations

-4(0.2) + y=-6

y=-6+0.8

y=-5.2

The only solution is (0.2,-5.2)
