a. Form a pair of simultaneous equations by letting y1 equal the left side and y2 equal the right side of sqrt 5-x=1.
b.Repeat part (a) with the equivalent equation sqrt 5=x+1
c. Repeat part (a) with the equivalent equation sqrt 5-x-1=0
so, what's the problem? Divide the equation in two and make new equations.
a. To form a pair of simultaneous equations with the equation sqrt(5-x) = 1, we can let y1 equal the left side (sqrt(5-x)) and y2 equal the right side (1).
So, the pair of simultaneous equations will be:
y1 = sqrt(5-x)
y2 = 1
b. To form a pair of simultaneous equations with the equivalent equation sqrt(5) = x+1, we can let y1 equal the left side (sqrt(5)) and y2 equal the right side (x+1).
So, the pair of simultaneous equations will be:
y1 = sqrt(5)
y2 = x + 1
c. To form a pair of simultaneous equations with the equivalent equation sqrt(5-x-1) = 0, we can let y1 equal the left side (sqrt(5-x-1)) and y2 equal the right side (0).
So, the pair of simultaneous equations will be:
y1 = sqrt(5-x-1)
y2 = 0
