ur supposed to add straight down, but then i think u have to multiply one equation by the other to get y to cancel out, and then i get up to that step, and then just get really confused, i really do appreciate any help...THANX
x+4=-2
x-y=2
Are you sure you copied the first equation correctly? There is no y term in it. It already tells you that x = -6
actually i did write it wrong, im sorry, but i already got the answer for it, thankyou for your time anyway..
To solve these equations, you can use the method of substitution. Here are the steps to follow:
Step 1: Solve one of the equations for x or y in terms of the other variable.
Let's solve the first equation, x + 4 = -2, for x:
x = -2 - 4
x = -6
Step 2: Substitute the expression you found for x into the other equation.
Replace x in the second equation, x - y = 2, with -6:
-6 - y = 2
Step 3: Solve the new equation to find the value of y.
To isolate y, add y to both sides:
-6 - y + y = 2 + y
-6 = 2 + y
Subtract 2 from both sides:
-6 - 2 = y
y = -8
Step 4: Substitute the value you found for y back into one of the original equations to find x.
Let's use the first equation again, x + 4 = -2:
x + 4 = -2
Subtract 4 from both sides:
x = -2 - 4
x = -6
So the solution to the system of equations is x = -6 and y = -8.
Remember, when solving a system of equations, it's important to follow each step carefully and double-check your work.
