Answer:
t=7
Step-by-step explanation:
t-27=-(27-7)---> remove parenthesis (multiply by -1)
t-27=-27+7-----> combine like terms
t-27=-20--------> add 27 to both sides
t=7

Answer:
<h3>
<u>
x = -7</u></h3>
Step-by-step explanation:
x-coordinate of both points is the same. That means the line is parallel to Y-axis
Equation of every line parallel to Y-axis is: x = x₀
where x₀ is the x-coordinate of any point from the line
x₀ = -7 so the equation is:
<u>x = -7</u>
