Answer:
13y - 55
Step-by-step explanation:
Given
7(3y - 5) - 2(10 + 4y) ← distribute both parenthesis
= 21y - 35 - 20 - 8y ← collect like terms
= 13y - 55
Answer:
When using the distributive property, we can operate parenthesis:
[tex]a*(b+c)=ab + ac[/tex]
So, in our case:
[tex]7(3y-5) -2(10+4y)[/tex]
[tex]7*3y+7*(-5) - 2*10-2*4y[/tex]
[tex]21y -35 - 20 - 8y[/tex]
[tex]=13y - 55[/tex]
So now we know the result is 13y - 55
