28-0.3y=0.7y-12 add 0.3y
+0.3y +0.3y
28=0.7y-12+0.3y
28=y-12 add 12
+12 +12
28+12=y
40=y
y=40 solved for y
+0.3y +0.3y
28=0.7y-12+0.3y
28=y-12 add 12
+12 +12
28+12=y
40=y
y=40 solved for y
Answer:
The value of the equation is [tex]y=40[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex] 28-0.3y=0.7y-12[/tex]
We need to solve the equation for y.
Add 0.3y to both sides of the equation.
[tex] 28-0.3y+0.3y=0.7y+0.3y-12[/tex]
[tex]28=y-12[/tex]
Add 12 to both the sides of the equation.
[tex]28+12=y-12+12[/tex]
[tex]y=40[/tex]
Hence, the value of the equation is [tex]y=40[/tex].
