The value of the x is -2 after solving the linear equation by using the elimination method.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear equations are:
2x+3y=8
6x−5y=−32
3X(2x+3y=8)
6x + 9y = 24
6x−5y=−32
14y = 56
y = 4
x = -2
Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

Answer:
126.5
Step-by-step explanation:
first, break the figure into a triangle and a square (do I have to tell u where)
the square: 11*8=88
the triangle: 11*7=77 77/2= 38.5
88+38.5= 126.5
The solution is, the area of the given figure is : 126.5cm^2.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
we need to find the area of the given figure.
so, we have ,
first, break the figure into a triangle and a square
now, we get,
the square:
area= 11*8
=88
and, we have,
the triangle:
area =1/2* 11*7
=1/2*77
= 77/2
= 38.5
so, we get,
the area of the given figure is:
88+38.5= 126.5
Hence, The solution is, the area of the given figure is : 126.5cm^2.

What is the slope of the line in the graph?
Answer:
-1 is the slope
Step-by-step explanation:
Take 2 points, you go down 2 and right 2 to get to the next point, so the slope is -2/2 = -1
Answer:-1
Step-by-step explanation:
Look at the two points. Now, look at how the line traveled to get from one point to the other, down two and over two, or -2/2. To simplify, divide by two, which gives you -1/1 or -1
