my answer - 3
is it correct???
Systems of Equations
y = 2x - 4
y = x - 1
please help!!! :'(
is it correct???
the x or the y
you have to find both
i already found the y which is..... 2
I get x = 3 , y =2
when i put my answer I put a dash, that's not a negative sign
Step 1: Start by expressing one equation in terms of one variable. Let's express the second equation, y = x - 1, in terms of x:
y = x - 1
Step 2: Now, substitute this expression for y in the first equation:
y = 2x - 4
x - 1 = 2x - 4
Step 3: Simplify the equation by combining like terms.
x - 2x = -4 + 1
-x = -3
Step 4: Multiply each term by -1 to isolate x:
-x * (-1) = -3 * (-1)
x = 3
Step 5: Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the second equation:
y = x - 1
y = 3 - 1
y = 2
So the solution to the system of equations is x = 3 and y = 2.
