3(x-7) = 138 + 3x First multiply
3x-21 = 138 + 3x subtract 3x from both sides
-21 = 138
This is a false statement because -21 does not equal to 138 so the answer is no solution.

65
Step-by-step explanation:
let's place 9 in place of p and 4 in place of q. I will use a star in place of that symbol for the sake of my convenience having to look for it, apologies.
I’m learning this right now so first you will subtract 8 on both sides of the equation. Then, rewrite it as 12y=2x-8. Next you will divide by 12 to each number when you are done then rewrite it as y=1/6x-2/3. Then for x you will divide by 2 on both sides and it would be x=6y+4. Well, that’s how I’m learning it I don’t know if that’s the same way you are learning it. But there you go
Step-by-step explanation:
We know:
The sum of the measures of acute angles in a right triangle is equal 90°.
Therefore
(1) A + B = 90°
(2) 90° + B + C = 180° - angles on a straight line
(3) from (2) B + C = 90° → B = 90° - C
(4) from (1) and (3) A + (90° - C) = 90° → A - C = 0
Therefore
A = C → ∠A ≅ ∠C
