In the form of algebra substitution is the method used in simultaneous equations.
E.g y=2x+5 and y=5x-1
Solve for x and y
Since we know two examples of what y is, we can substitute one y in replacement of the other to get.
2x+5=5x-1 then we solve for x to get:
x = 2 sub this back in to get y = 2(2) +5
y = 9
Is this more then one question?

Step-by-step explanation:
The measure of APL is around 23% sorry that I can’t find the exact number I kind of forgot how to do this lesson
<span>Height of triangle = y1 </span>
<span>Base of triangle = x2 - x1 </span>
<span>Area = 1/2 * (x2 - x1)*y1 </span>
<span>1/2 y1 (x2−x1)</span>
