An equation is formed of two equal expressions. The solution of the system of equations is (0.75, 1.25).
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution to the system of equation is,
y = 2 - x
y = 3x - 1
Substitute the value of y,
y = y
2 - x = 3x - 1
2 + 1 = 3x + x
3 = 4x
x = 3/4 = 0.75
Substitute the value of x in any one of the equation,
y = 2 - x
y = 2 - 0.75
y = 1.25
Hence, the solution of the system of equations is (0.75, 1.25).

Answer:
1.3905 × 10^4
Step-by-step explanation:
First you should multiply all the two numbers inside the parentheses
5.7 × 105=598.5
4.6 × 106=487.6
2.9 × 105=304.5
Now add the three numbers
598.5+487.5+304.5= 1390.5
scientific notation: Put the decimal after the first digit. To find the exponent count the number of places from the decimal to the end of the number.
the answer in scientific notation: 1.3905 × 10^4
Answer:
x = 40
Step-by-step explanation:
The angles are vertical angles which mean they are equal
3x=120
Divide each side by 3
3x/3 = 120/3
x = 40
