We must simplify the expression:
[tex]2y-6\left(5z-5y\right)+z[/tex]1) First, we apply the distributive property of multiplication with the terms in the parenthesis:
[tex]2y+(-6)\cdot5z+(-6)\cdot(-5y)+z.[/tex]2) Doing the multiplications, we get:
[tex]2y-30z+30y+z.[/tex]3) Summing the terms with z and the terms with y, we get:
[tex](2y+30y)+(z-30z)=32y-29z.[/tex]Answer32y - 29z
