Answers: y= 5x-4
Step-by-step explanation:
Steps:
[y=5x-4
12=15x-3y]
Substitute y=5x-4
[ 12=15x-3(5x-4) ]
Simplify
The solution is
y= 5x-4
12000m=12km 3l=0.003cl 7000ml= 7l 1kg=1l 1100cl=11L 7000L = 7k 9cl=90ml 6g=600 cg
Answer:
12
Factors of 30: 1,2,3,5,(6),10,15,30
Factors of 42: 1,2,3,(6),7,14,21,42
30 divided by 6, 42 divided by 6
(5) + (7)= 12
This has one real solution, x=4
8 - 4x = 0
Add 4x to each side
8 - 4x+4x = 0+4x
8 =4x
Divide each side by 4
8/4 = 4x/4
2 =x
