Hey there! :)
Equation 1) 4x = y - 1
Equation 2) 6x - 2y = -3
We want both equations to match in a sense where both x & y are on the same side of the equal sign. To achieve this, simply subtract y from both sides in equation 1.
This will leave us with : 4x - y = -1
Now, line up the equations with one another.
1) 4x - y = -1
2) 6x - 2y = -3
Now, multiply 2 to ALL of equation 1.
2(4x - y = -1)
Simplify.
8x - 2y = -2 → We'll call this new equation 3. Now, line up equation 3 with equation 2.
6x - 2y = -38x - 2y = -2
Subtract equations from one another.
-2x = -1
Divide both sides by -2.
-2x ÷ -2 = -1 ÷ -2
Simplify.
x = 1/2
Now, plug in 1/2 for x into our first equation.
4x - y = -14(1/2) - y = -1
Simplify.
2 - y = -1
Subtract 2 from both sides.
-y = -1 - 2
Simplify.
-y = -3
Divide both sides by -1.
y = 3
So, our answer is : x = 1/2, y = 3 OR (1/2, 3)
~Hope I helped!~
Answer: 
Step-by-step explanation:
Given: Fraction of 7th graders got A = 
Fraction of 7th graders got B = 
The fraction of the students got an A or B = Fraction of 7th graders got + Fraction of 7th graders got B
Hence, the required fraction:
Answer:
I think last year, the company's profit was 2.3 million $
Step-by-step explanation:
5.8 - 1.2 = 4.6
4.6 divided by 2 = 2.3
Answer:
x = 26
Step-by-step explanation:
Start with - 9 + x = 17, or -9 + x = 17
Solve for x by isolating x on the left side. To do this, add 9 to both sides, obtaining x = 26
First, add 12 to both sides of the equation,
-3y - 12 + 12 = -4 + 12
-3y = 8
Then, divide both the left hand and right hand sides of the equation by -3
(-3y) / -3 = 8/-3
The value of y is therefore,
y = -8/3
