Question

Given m || n, find the value of x and y

Answer 1

x=16 and y=9

Explanation:

(x+19)+(9x+1)=180

Combine Like Terms

10x+20=180

Subtract 20 from both sides

10x=160

Divide 10 by both sides

x=16

Fill in for x in (9x+1) to help find y

9*16+1

145

3y+8+145=180

Combine like terms

3y+153=180

Subtract 153 from both sides

3y=27

Divide 3 by both sides

y=9
