Answer:
x = All Real Numbers
Step-by-step explanation:
5x + 5 + x = 6x + 5
Subtract 5 from both sides
5x + x = 6x
Add the x
6x = 6x
x = Any number in the world
Hope that helps!
Answer:
x=50
Step-by-step explanation:
3x-5=145(vertically opposite angle)
3x=145+5
3x=150
x=150/3
x=50
DON'T FORGET TO WRITE DEGREE
Answer:
There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.
Answer:
m^2+4m-21
Step-by-step explanation:
(m-3)(m+7)
m^2-3m+7m-21
m^2+4m-21
Answer:

Step-by-step explanation:
We know that the sum of Angle S and Angle T is 120. So:

The measure of Angle S is (4x + 30).
And the measure of Angle T is (30).
We want to find the value of <em>x</em>.
By substitution:

Combine like terms:

Subtract 60 from both sides:

Divide both sides by 4:

Hence, the value of <em>x </em>is 15.
