after solving the given systems of equations we get x = 5 and y = -1
Step-by-step explanation:
We need to solve the following systems of equations.
Let
Multiply equation 1 by 3 and equation 2 by 4 and subtract both:
So, Value of y is y = -1
Now putting value of y in equation(1)
So, value of x is x = 5
so, after solving the given systems of equations we get x = 5 and y = -1

Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
