Answer:
<1 = <2 because...
We know that <1 = 90. So <2 = 90 since <1 and <2 form a linear pair.
Step-by-step explanation:
x+y=12
x-y=4
Then you solve:
x+y=12
-y -y
x=12-y
x-y=4
+y +y
x=4+y
4+y=12-y
+y +y
4+2y=12
-4 -4
2y=8
divide both sides by 2 to isolate y
y=4
Plug it into one of the equations
x+4=12
-4 -4
x=8
Answer:
Look below
Step-by-step explanation:
To verify that the solution is (3,4) we can plug the numbers back into the equation.
Remember that the solution to a linear equation is represented in the form (x,y). Therefore we plug 3 in for x and 4 in for y.
4=3+1
4=4 Correct!
Now we need to check the second equation
4=-2(3)+10
4=-6+10
4=4 Correct!
Therefore the solution is (3,4)
