Answer:
One solution
Step-by-step explanation:
3x - 5 = - 3
1. Add 5 to both sides
3x= 2
Then Divide by three to get x alone
x= 2/3
X has only one solution here
Answer:
i would put something like:
s = 650 + 19w * 60
and the total is:
1790
Step-by-step explanation:
3x - 4y = 7 ; Solve for x
We're essentially just trying to get "x" onto it's own side.
So, in order to do this, we must get "y" onto the other side of our equal sign.
Add 4y to both sides.
3x = 4y + 7
Then, we divide 3 from both sides.
x = 4/3y + 7/3
15y + 1 = x ; Solve for y.
Instead of solving for x, we are now solving for y :)
So, in order to isolate y, we must subtract 1 from both sides.
15y = x - 1
Then, divide both sides by 15.
y = 1/15x - 1/15

Answer:
x=145
Step-by-step explanation:
There are two ways to solve:
-Vertical angles Theorem states that opposite angles are congruent, so x=145 degrees.
-Sameside angles are supplementary so:
35+x=180
Subtract 35 from both sides:
x=145
