SAT practice: Find the solution (x, y) to the system of equations below, what is the value of x-y (show work) 7x + 3y = 8
Y= 2x - 5/3

Substitute the given value of x into the first equation

To solve for x distribute 3 though the parentheses

Collect like terms

Move the constant to the right-hand side and change its sign

Add the numbers

Divide both sides of the equation by 13

Now, Substitute the given value of x into the second equation

Plug in the value of x in the equation i.e. 1

Any number multiplied by 1 results in number itself

Calculate the difference

The possible solution of the system is the ordered pair (x,y)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

24/56=hx^7
