y=3x+16

4x-5y=-25

substitute the given value of y into the equation.

4x-5(3x+16)=-25

solve

x=5

substitute the given value of x into the equation.

y=3x(-5)+16

solve

Answer:

x=-5

y=1

Step-by-step explanation:

4x-5y=-25

4x-5(3x+16)=-25

-11x-80=-25

-11x-80+80=-25+80

-11=55

-11x/-11=55/-11

x=-5

y=3x+16

y=3(-5)+16

y=-15+16

y=1

Simplify the following algebraic expression:<br> 4+3 [6z - 5(6 +2z)]

Tatiana [17]

$\huge\text{Hey there!}$

$\huge\text{4+3 [6z - 5(6 +2z)]}$

$\huge\text{4+(3)(6z)+(3)(-5(6+2z))}\\\\\rightarrow\huge\text{4+18z+(-30z)+(-90)}$

$\huge\text{\bf{Combine the like terms if you have any.}}$

$\huge\text{Like term \#1: 10z \& -30z}\\\\\\\huge\text{Like term \#2: 4 \& -90}$

$\huge\text{18z + (-30z) + (4 + (-90))}$

$\huge\text{18z + (-30z) = -12z}\\\\\\\huge\text{4 + (-90) = -86}$

$\boxed{\boxed{\huge\text{Answer: -12z + (-86)}}}\huge\checkmark$
