The distance on a numberline from -10 to 3 is equal to 5x-12.
Viefleur [7K]

Answer:

  1. 13
  2. x = 5

Step-by-step explanation:

To find the total distance, we can add.

10 + 3 = 13

Now, we can use 13 to solve for the equation that is the same.

5x - 12 = 13

5x = 25

x = 5

Best of Luck!

How do you solve substitution to solve the sytem <br> x+y=2<br> -2x+y=2
lord [1]
So you want to make one of the equations equal to one of the placeholders exg y=x+3

so we have
x+y=2 and
-2x+y=2

I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x

subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0

subsitute x=0 in x+y=2
0+y=2
y=2

x=0
y=2
