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
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
x = 2
