Answer:
D.) 57
Step-by-step explanation:
x=o
in other words the two angles are equal
Answer: x = (-3,3), y = (-5,5)
Step-by-step explanation:
Add both of the equations together, for . Now we can divide both sides by 3, getting. we subtract the first equation from our equation we just got, getting y= (5,-5). once we plug that in, we get , x = (-3,3)
Given the system of equations:
To solve it by substitution, follow the steps below.
Step 1: Solve one linear equation for x in terms of y.
Let's choose the second equation. To solve it for x, add 3y to each side of the equations.
Step 2: Substitute the expression found for x in the first equation.
Step 3: Isolate y in the equation found in step 2.
To do it, first, add 48 to both sides.
Then, divide both sides by 15.
Step 4: Substitute y by 5 in the relation found in step 1 to find x.
Answer:
x = -9
y = 5
or (-9, 5)
Also, you can graph the lines by choosing two points from each equation, according to the picture below.
