Looks good! From what i see unless i missed something it all looks correct :D
Answer:
a = 5
Step-by-step explanation:
3(a - 4) + 1 = 9 - a Distribute the 3 into a-4
3a - 12 + 1 = 9 - a Combine like terms
[-12 and 1]
3a - 11 = 9 - a Add 11 to both sides to isolate 3a
+11 +11
3a = 20 - a Add a to remove it and have all a
+a +a
4a = 20 Divide by 4 to only have a
/4 /4
a = 5
Answer:
C. No solutions
Step-by-step explanation:
5x - 3 = 5 (x - 1)
5x - 3 = 5x - 5
* so they have the same slope but different y-intercepts. So they would be parallel lines and they would never intercept meaning. No Solutions!
I'd suggest getting a Texas Instruments TI-84 plus calculator or use des mos .com scientific
