Answer:
<u>x = 12</u>
Step-by-step explanation:
10 - 3 ( x + 7 ) = 26
<em>First Step: Distribute</em>
- 3 to ( x + 7 )
= 10 - 3 x - 21 = 26
<em>Second Step: Combine like terms</em>
10 - 21
= - 11 - 3 x = 26
<em>Third Step: Add from both sides</em>
26 + 11
= - 3 x = 37
<em>Fourth Step: Divide from both sides</em>
37 / - 3
<u>x = 12</u>
It seems that some the work is already here, but I'd be glad to!! So for #3 which is 9x^2+15x, we can factor out both a 3 and an x (3x) so we know that 3x * 3x =9x^2 and 3x * 5 = 15x so once we take the 3x out of the equation, we are left with 3x(3x+5) and that's as far as you can factor.
For #4, we see that the common factor is 10m because 10m * 2n = 20mn and 10m * 3 = 30m so once we take 10m out of the original, it becomes 10m(2n-3)
For #5, this one the common factor is 4xy because 4xy * 2xy=8x^2y^2 and 4xy*x= 4x^2y and 4xy*3=12xy so once we take the 4xy out of the equation, it becomes 4xy(2xy-x-3)
Hope this helps!
