How do you do it?:(
im stuck!
y=-x+4
y=-1/5x
umm what are u solving for?
there is no question present here?
are u solving for x?
if yes then\\make em equal each other
y=y
so
-x+4=-1/5x
frst get rid of the 5-multiply both sides by 5
-5x+20=-1x
isolate x
20=-1x+5x
20=4x
5=x
9=-3/8r
To solve the system of equations y = -x + 4 and y = -1/5x, you can use the substitution method. Here's how to do it:
Step 1: Start by expressing one equation in terms of one variable. Let's choose the second equation, y = -1/5x, and solve it for y.
y = -1/5x
Step 2: Take this expression for y and substitute it into the other equation for y.
-1/5x = -x + 4
Step 3: Solve the resulting equation for x.
Multiply both sides of the equation by 5 to get rid of the fraction.
-x = -5(-x + 4)
-x = 5x - 20
Combine like terms.
4x = 20
x = 5
Step 4: Substitute the value of x back into one of the original equations to find the corresponding value of y. Let's use the first equation, y = -x + 4.
y = -(5) + 4
y = -5 + 4
y = -1
Step 5: Check your solution by substituting the values of x and y into the other equation. If both sides of the equation are equal, then the solution is correct.
Substituting x = 5 and y = -1 into the second equation y = -1/5x:
-1 = -1/5(5)
-1 = -1
Since both sides are equal, the solution is correct.
Therefore, the solution to the system of equations is x = 5 and y = -1.
