HELP PLS<br> Solve for x<br> x=[?]<br> 3x + 2 6x - 20

Sloan [31]

Step-by-step explanation:

Therefore 3x + 2 + 6x - 20 = 180.

=> 9x - 18 = 180

=> 9x = 198

=> x = 22.

Solve the linear expression 5(-3.4k-7)+(3k+21)

Ksivusya [100]

Our expression is below

$5(-3.4k-7)+(3k+21) = 0$

by solving it for the value of k

$(-17k-35)+(3k+21) = 0$

$-17k+3k-35+21 = 0$

$-14k-14 = 0$

$-14k = 14$

$k = \frac{14}{-14}$

$k = -1$
