Answer:

  • 28 = -3k + 7

28 - 7 = -3k

21 = -3k

21/-3 = k

k = -7

  • 1/5  x - 17 = 3

x/5 = 3 + 17

x/5 = 20

x = 5*20

x = 100

  • 82 = 7/10 G + 12

82 - 12 = 7G/10

70 = 7G/10

70*10 = 7G

700 = 7G

700/7 = G

G = 100

Solve |-x + 4 | = | 2x - 2| by graphing<br> P/s: if possible show me how to do it T-T
sertanlavr [38]
I always like to start by removing the absolute value signs. Solving the two equations, -x+4 = 2x-2 we get 6 = 3x, x = 2
If we test ±2 we get the following:
x = 2; | -(2) + 4 | = | 2(2) - 2 |, | 2 | = | 2 |, 2 = 2
Now we test
X = -2; | -(-2) + 4 | = | 2(-2) - 2 |, | 6 | = | -6 |, 6 = 6
Both +2 and -2 work.

18x + 101 = 4<br> 91 – 51'= -1<br> help me pleasee
juin [17]

Distribute the -9 into the values in the parentheses.

STEP BY STEP

-9(-2x-3)

-9*-2x=18x

-9*-3=27

Therefore, the equation then becomes: 18x+27.

The answer is the first choice, or A.
