Answer:

x = 86

y = 94

Step-by-step explanation:

The angle that measures 86 degrees and x are alternate exterior angles, which means they're equal.

The 86 degree angle and y add up to 180 degrees, since the lines are parallel. So,

180 - 86 = 94

How many solutions are there to the<br>system of equations, x + y = 1<br>and 2x + 2y = 2?

larisa86 [58]

There are infinitely many solutions of the system of equations, x + y = 1

and 2x + 2y = 2

Step-by-step explanation:

We need to find how many solutions are there to the system of equations.

$x+y=1\,\,\,(1)\\2x+2y=2\,\,\,(2)$

Solving:

Multiply equation (1) with 2 and subtract with equation(2)

$2x+2y=2\\2x+2y=2\\-\,\,-\,\,\,\,\,\,\,\,\,\,\,\,-\\------\\0=0$

Since our answer is 0=0 so, there are infinitely many solutions.

Find the solutions of 6(2-7x)+x(7x-2=0)

azamat

$6(2-7x)+x(7x-2)=0$

Use distributive property: a(b - c) = ab - ac

$(6)(2)-(6)(7x)+(x)(7x)-(x)(2)=0\\\\12-42x+7x^2-2x=0\\\\7x^2-44x+12=0\\\\7x^2-42x-2x+12=0\\\\7x(x-6)-2(x-6)=0\\\\(x-6)(7x-2)=0\iff x-6=0\ \vee\ 7x-2=0\\\\x-6=0\ \ \ |+6\\\\x=6\\\\7x-2=0\ \ \ |+2\\\\7x=2\ \ \ |:7\\\\x=\dfrac{2}{7}$

Answer:\ $x=6\ \vee\ x=\dfrac{2}{7}$
