Answer:
When simplifying using addition and subtraction, you combine “like terms” by keeping the "like term" and adding ... Solve the following equations for x: 1) x + 5 = 12. 2) x – 11 = 19. 3). 22 – x = 17 ... To get the x by itself, you will need to get rid of the 5 and the 3. ... We check the answer by putting it back in the original equation:.
Step-by-step explanation:
-2k+4=10
1st, subtract 4 from both sides so that it'll cancel out. -2k=6
2nd. divide by -2. K=-3

Answer:
x=-2
Step-by-step explanation:
-2x-7=3(4x+7)
distribute
-2x-7 = 3*4x +3*7
-2x-7 = 12x+21
add 2x to each side
-2x-7+2x = 12x+2x+21
-7 = 14x+21
subtract 21 from each side
-7-21 = 14x+21-21
-28 = 14x
divide by 14
-28/14 = 14x/14
-2 =x
