Answer:
x = -50/9
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 8 - 12x = 42
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: -9x - 8 = 42
- Isolate <em>x</em> term: -9x = 50
- Isolate <em>x</em>: x = -50/9
Answer:
E. -8, -29
Step-by-step explanation:
a-b=21
5a -2b =18
Take the first equation and solve for a by adding b to each side
a-b=21
a-b+b=21+b
a = 21+b
Now substitute a=21+b into the second equation
5a -2b =18
5(21+b) -2b =18
Distribute the 5
105 +5b-2b =18
Combine like terms
105 +3b =18
Subtract 105 from each side
105-105 +3b = 18-105
3b = -87
Divide each side by 3
3b/3 =-87/3
b = -29
if b = -29, we can substitute it into a =21+b
a = 21-29
a = -8
Answer:
10 1/9
Step-by-step explanation:
To make it easier to answer, make both of them into an improper fraction
4 1/5 = 21/3
1 4/9 = 13/9
Now we can multiply them easier
21/3 x 13/9 = 273/27
27 goes into 273 10 times and the left over is 3 so the mixed fraction would be
10 3/27, to simplify
10 1/9
