Answer:
[tex]-12y+20[/tex]
Step-by-step explanation:
[tex]\left(4-5y\right)-2\left(3.5y-8\right)[/tex]
Use distributive property.
[tex]-2\left(3.5y-8\right)[/tex]
[tex]-2\cdot \:3.5y-\left(-2\right)\cdot \:8[/tex]
[tex]-7y+16[/tex]
[tex]4-5y-7y+16[/tex]
Now, add like terms.
[tex]-5y-7y=-12y[/tex]
[tex]\:4+16=20[/tex]
[tex]-12y+20[/tex]
