System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3
I hope this help you
Answer:
C
Step-by-step explanation:
A. (4+16)/2 = (4+10+16)/3 =10
Answer:
<h2>34 degrees</h2>
Basic facts:
<em>Corresponding angles are sometimes known as 'F' angles.</em>
angles in a straight line add up to 180
Step-by-step explanation:
To find the other side of <em>a</em> we follow the Basic fact annd do
180-146
=34
following the rule, we know that this is a flipped F
An F is a corresponding angle
therefore f is 34
