Answer:
x= -3/5
Step-by-step explanation:
4x-2y=14
y=12x-1
4x-2(12x-1)=14
4x-24x+2=14
4x-24x=12
-20x=12
×= -12/20
x= -3/5
200 times. Because 1000 divided of 5 is 200. You could divide it using the algorithm.
1/2*2a= 1a
-6b*1/2=-3b
8* 1/2= 4
so 1a-3b+8
Second side= x
First side = 2x
Third side = x+5
x+2x+x+5=49
4x=44
x=11
1st side= 22
2nd side = 11
3rd side = 16
The answer is 155 . 234-79=155 !
