Answer:
19a+27b-54
Step-by-step explanation:
First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.
28a+21b-42
Then do the same for -3 and (3a-2b+4).
-9a+6b-12
Rewrite the equation 28a+21b-42-9a+6b-12.
Combine like terms: 19a+27b-54
Answer:
1) y = 3x+5
2) y = 
3) y = -x + 0
4) y = 
5) y = 
Step-by-step explanation:
y = mx+b
In slope-intercept form, these are important to know:
- y and x should stay as variables
- m = slope of the line
- b = y intercept
Using the facts above⬆, we can solve these problems
Remember: Substitute m and b using the given information
1) y = 3x+5
2) y = 
3) y = -x + 0
4) y = 
5) y = 
Hope this helps :)
Have a great day!
-6(4x + 1) + 7x + 9(x - 3) = 4
-6(4x) - 6(1) + 7x + 9(x) - 9(3) = 4
-24x - 6 + 7x + 9x - 27 = 4
-24x + 7x + 9x - 6 + 27 = 4
-8x + 21 = 4
- 21 - 21
-8x = -17
-8 -8
x = 2.125
