Answer:

Option C is correct.

Step-by-step explanation:

$- 2x + 4.4 = 23.8$
$- 2x = 23.8 - 4.4$
$- 2x = 19.4$
$x = - \frac{19.4}{4.4}$
$x = - 9.7$

Y = 2x + 4 16x + 4y = 40

Dafna11 [192]

Y = 2x + 4
16x + 4y = 40

substitute Y = 2x + 4 into 16x + 4y = 40

16x + 4y = 40
16x + 4(2x + 4) = 40
16x + 8x + 16 = 40
24x = 40 - 16
24x = 24
x = 1

Y = 2x + 4
Y = 2(1) + 4
Y = 6

answer (1, 6)

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive
