Solve the inequality -×/7+4>3×.

agasfer [191]

The expression is no very clear.

It seems to be - x / 7 + 4 < 3x

If so, this is the solution.

1) 3x + x / 7 > 4

2) 21x + x > 28

3) 22x > 28

4) x > 28/22

5) x > 14/11

Answer: x > 14 / 11

What is the solution to this system of linear equations? 7x – 2y = –6 8x y = 3 (–6, 3) (0, 3) (1, –5) (15, –1)

erik [133]

Answer:

$(0,3)$

Step-by-step explanation:

we have

$7x-2y=-6$ ----> equation A

$8x+y=3$ ----> equation B

Multiply the equation B by 2 both sides

$2(8x+y)=2*3$

$16x+2y=6$ ------> equation C

Adds equation A and equation C

$7x-2y=-6\\16x+2y=6\\--------\\7x+16x=-6+6\\23x=0\\x=0$

Find the value of y

$7(0)-2y=-6$

$-2y=-6$

$y=3$

the solution is the point $(0,3)$
