I say 1 1/4 because 4 1/12 vs 3 1/3 I just did common denominator
Using elimination method, the value of system of equations x = 1 and y = -3.
<h3>How to solve the equations by the
elimination method?</h3>
When solving a system of equations using the elimination method, the first step is to make the coefficient of one of the variables to be equal.
Given;
2x + y = -1
4x - y = 7
Add both the equation, we get
2x + y + 4x - y = -1 + 7
6x = 6
x = 1
Also,
2x + y = -1
y = -1 - 2
y = -3
Therefore, the value of x = 1 and y = -3.

∠ WVS and ∠ UVX are vertical angles and congruent, then
∠ UVX = 126.8°
Answer:
<h3>I'm pretty sure it's 40x + 150 in²</h3>
Step-by-step explanation:
The side length includes 4 x's and 3 (5's). Multiplying these by ten we get 4x times 10 which is 40x and 15 * 10 which is 150. Also in an area problem the unit is always squared.
Answer:
x = 3 and y = 0
Step-by-step explanation:
To find the solution where you have two equations is called a System of Equations.
What you do is you notice there are two equations and the let both equations equal each other. We can do this because both equations start with a y. These "y" work like puzzles and you can connect the "x+3" and "2x + 6" together. Then solve for it. Here's what i mean,
y = x+3
y = 2x+6
Now connecting them,
x+3 = 2x+6
Subtract x from both sides
3 = x + 6
Subtract 6 from both sides,
x = -3
Now solve for y,
y = -3 + 3 = 0
So our solution is x = 3 and y = 0.
