Solve the system of equations using the substitution method. {y=−3x+7 x=−2y−16 enter your answers in the boxes. x= y=

ANSWER

EXPLANATION

The given system of equations is

and

We substitute equation (1) into equation (2) to get;

We group similar terms

Divide both sides by -5.

Put x=6 into equation (1).

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: no
