Answer:
- Equation 1 has exactly one solution.
- Equation 2 has infinitely many solutions.
- Equation 3 has no solution.
Step-by-step explanation:
We are given three equations to solve. First, let's solve the equations for x.
<u>Equation 1</u>
<u />
<u />
Therefore, we determined that for the first equation, x = -5. We can check our solution by substituting it back into the original equation.

Since we got a true statement, there are no other values of x for which we get a true statement. Let's test this with the opposite value: positive 5.

Therefore, for Equation 1, there is exactly one solution.
<u>Equation 2</u>
<u />
<u />
We get a true statement by solving for x (which ends up canceling out of the equation entirely). Therefore, we can check <u>any value</u> in place of x to see if we get a true statement. For this instance, I will use -3.

We still get a true statement, so Equation 2 has infinitely many solutions.
<u>Equation 3</u>
<u />
<u />
We get a false statement. Therefore, Equation 3 has no solution.
1,925 is close to 2,000
so 2,000 x 7 = 14,000
1,925 x 7 = ?
5 x 7 = 35
20 x 7 = 140
900 x 7 = 6,300
1,000 x 7 = 7,000
so 7,000 + 6,300 + 140 + 35 = 13,475 and 13,475 is close to 14,000 or 13,500 or 13,470.
Hope this helps even though a little confusing! ;D

Answer:
4=x
Step-by-step explanation:
y=-x+4
y=2x-8
-x+4=2x-8
+x +x
4=3x-8
+8 +8
12=3x
/3 /3
4=x
