Yas! systems of equations
convert one equation so that a single variable is one one side
x = 65 - 2y
plug it in the other equation
2(65 - 2y) + 3y = 105
130 - 4y + 3y = 105
130 - y = 105
25 = y

A classmate wrote the solution to the inequality |-4x + 1| > 3 as show below. Describe and correct the error.

andrezito [222]

Answer:

See below.

Step-by-step explanation:

The last step is incorrect. When we divide both sides by a negative the inequality is flipped. The answer is x < -1/2.

Also they omitted the other possibility that the expression in the vertical lines could be negative.

We also have the inequality

- 4x + 1 < - 3

-4x < -4

x > 1.
