Answer 1

Answer:

Step-by-step explanation:

15x-21-18x-22=10

-3x-1=10

-3x=11

x=-11/3

Answer 2

Solution:

$3(5x-7) -2(9x11) = 10$

$Expand\: 3(5x-7)-2(9x-11): -3x+1$

$-3x+1=10$

$Subtract\: 1\: from\: both\: sides$

$-3x+1-1 = 10-1$

$Simplify$

$-3x = 9$

$Divide \: both \: sides \: by-3$

$\frac{ - 3x}{ - 3} = \frac{9}{ - 3}$

$Simplify$

$X = -3$ is the answer
