Answer:

3.666666667 + 2.333333333y

Step-by-step explanation:

Simplifying

3x + -7y = 11

Solving

3x + -7y = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

3x + -7y + 7y = 11 + 7y

Combine like terms: -7y + 7y = 0

3x + 0 = 11 + 7y

3x = 11 + 7y

Divide each side by '3'.

x = 3.666666667 + 2.333333333y

Answer:

The solution of the system is

x=8, y=11

Step-by-step explanation:

we have

y = 2x-5 ----> equation A

y = x+3 ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The intersection point is (8,11)

see the attached figure

therefore

The solution of the system is

x=8, y=11

Find the perimeter of the rectangle whose adjacent sides are 3x-5y-4z and x-3y+5z
Kazeer [188]
<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ I'm assuming the answer is to be left in algebraic form.

Perimeter = length + length + width + width or (2 x length) + (2 x width)

Substitute the values in:

Perimeter = 2(3x - 5y - 4z) + 2(x - 3y + 5z)

Simplify:

Perimeter = 6x - 10y - 8z + 2x - 6y + 10z

Perimeter = 8x - 16y + 2z <== this is the answer
