Answer:
x = -3
Step-by-step explanation:
First solve it:
Subtract the x's from both sides
2y = -3x +8
2y = -5x +2
Divide by two
y= -1.5x + 4
y = -2.5x +1
set them equal to each other:
-1.5x +4 = -2.5x +1
Add 2.5 x to both sides
1x +4 = 1
x +4 = 1
subtract 4 from both sides
x = -3
11 cow and 19 chicken 11*4=44 19*2=38 38+44=82
5x-50= 30-15x
20x= 80
x= 4 is the solution to this problem
Answer in explanation
Step-by-step explanation:
for each row, the y- coordinate of the point where the line crosses the x- axis is zero. The point where the line crosses the x- axis has the form (a,0) ; and is called the x-intercept of the line. The x- intercept occurs when y is zero. Now, let's look at the points where these lines cross the y-axis
