PLS HELP CHECK :(
Check and answer I'm confused

Step-by-step explanation:

3(10-x) = 3*10 - 3*x = 30 - 3x

When x = 3,  -5x + 2 = -5*3 + 2 = - 15 + 2 = -12

-6x - 7 = 11 { add 7 to both sides}

-6x - 7 + 7 = 11+7

-6x = 18  {divide both sides by -6}

-6x/-6 = 18/-6

x = -3

3x + 10 = -20   {subtract 10 from both sides}

3x +10 - 10 = -20 - 10

3x = - 30 {divide both sides by 3}

3x/3x = -30/3

x = -10

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
