Answer:
Step-by-step explanation:
11) add 20 to both sides, x=-3
12) divide both sides by -8, v=18
13) divide both sides by -7, n=19
14) multiply both sides by 9, n=171
Answer:
11. x= -3
12. v=8
13. n=19
14. n=171
Step-by-step explanation:
11. 20+3=23, but since the answer is negative, the 3 has to be negative (different signs = negative)
12. 144/8 = 8, since product is negative, the answer has to be positive (different signs = negative)
13. 133/7= 19, answer must be positive because product is negative (different signs= negative)
14. 9*19=171, so therefore 171/9=19

3x + 2 ( 2x + 9 ) = 4
Answers
Answer:
3x + 2 (2x + 9) = 4
3x + 4x + 18 = 4
7x + 18 = 4
7x = -14
x = -2
Step-by-step explanation:
i think it should be -2. if im wrong sorry
Take care of the parenthesis to get the following
3x + 4x + 18 = 4
Add the X values
7x + 18 = 4
Take 18 from both sides so it looks like this
7x = 4 - 18
From this you’ll get this
7x = -14
Divide both sides by 7
x = -14 / 7
Simplify
X = 7 * - 2 / 7
Simplify
X = -2
