Answer:

Step-by-step explanation:
we have
<em>The equation of the first line</em>
------> equation A
<em>The equation of the second line</em>
------> equation B
Solve the system of equations by elimination
Multiply equation A by -4 both sides
--------> equation C
Adds equation B and equation C

<em>Find the value of x</em>
substitute the value of y


Multiply by 3 both sides


therefore
The solution to the system of equations is the point 
Answer:
x = 5
y = 7
Step-by-step explanation:
<em>Since they are both equal to </em><em>y</em><em>, we can set them equal to each other.</em>
2x - 3 = x + 2
<em>Combine like terms and isolate the </em><em>x</em><em>.</em>
x = 5
<em>Plug in the x to either equation to get the value of </em><em>y</em><em>.</em>
y = (5) + 2
y = 7
Answer:
180 in²
Step-by-step explanation:
the area of a rectangle = length × width
here length = 15 in and width = 12 in, hence
area = 15 × 12 = 180 in²
Answer:
-2y+x
Step-by-step explanation:
