Question

Use elimination but HURRY

Answer 1

Answer:

The solution of the system is the point (-2,4)

Step-by-step explanation:

we have

$2x-\frac{3}{4}y=-7$ ---> equation A

$x+\frac{1}{2}y=0$ ----> equation B

Solve the system by elimination

Multiply the equation B by -2 both sides

$-2(x+\frac{1}{2}y)=-2(0)$

$-2x-y=0$ ----> equation C

Adds equation A and equation C

$2x-\frac{3}{4}y=-7\\-2x-y=0\\--------\\\\-\frac{3}{4}y-y=-7\\\\-\frac{7}{4}y=-7\\\\y=4$

Find the value of x

substitute the value of y in any equation

$x+\frac{1}{2}(4)=0$

$x+2=0$

$x=-2$

The solution of the system is the point (-2,4)
