Step-by-step explanation:

.3 (4 - x) = x- 1.4

distribute.3 to 4 and -x

1.2 -.3x = x- 1.4

+.3x +.3x

1.2 = 1.3x -1.4

+1.4 +1.4

2.6 = 1.3x divide

/1.3 /1.3

2 = x put x to the right side because teachers like that

Answer:

x=2

Step-by-step explanation:

0.3(4-x)=x-1.4

1.2-0.3x=x-1.4

1.2-0.3x-x=-1.4

1.2-1.3x=-1.4

1.3x=1.2-(-1.4)

1.3x=1.2+1.4

1.3x=2.6

x=2.6/1.3

x=2

16. i’m pretty sure cause the ratio would be 42/24 28/x if you divide PQ by LM, the answer is the same number you would use to divide LM to get MN and finish your ratios
