Answer:
One Solution
Step-by-step explanation:
First substitute the y in the first equation with the second equation to get
-2x-4=3x+3
since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get
-4=5x+3
subtract the constant on both sides to get
-1=5x
divide both sides by 5
x= -0.2 or -1/5

Answer:
A. How many paperback books each person buys.
Step-by-step explanation:
In the equation the x represents how many paperback books they can buy.
In the equation the 2 represents that 1 hardcover book was purchased.
In the equation the 35 represents how much money they spent in total.
The equation is complete except for x which has to be substituted with how many paperback books they can buy. Which would be 5.

Solution for the system of linear equations is (4, - 3)
<u>Step-by-step explanation:</u>
Step 1:
Given system of equations
x - 3y = 13 -------- (1)
2x + 4y = - 4 ----- (2)
Step 2:
Multiply eq(2) with 2 to make coefficients of x equal.
2x - 6y = 26 ------ (3)
Step 3:
Subtract eq(2) from eq(3)
⇒ - 10y = 30
⇒ y = -3
Step 4:
Find value of x by substituting value of y in eq(1)
⇒ x - 3 × (-3) = 13
⇒ x + 9 = 13
⇒ x = 4
