Answer:
When finding the value of x let y be 0 and when finding value of y let x be 0 and get your answers.
Answer:
The answer to your question is: x = 7; y = 6
Step-by-step explanation:
2x+y=20 ( 1 ) Multiply by 5
6x−5y=12 ( 2 )
5 (2x+y=20) = 10x + 5y = 100
10x + 5y = 100
6x − 5y = 12 Eliminate y
16 x = 112
x = 112 / 16
x = 7
2(7) + y = 20 Substitution
14 + y = 20
y = 20 - 14
y = 6

Answer:
The answer to your question is:
Step-by-step explanation:
1.-
y = 84°
5x - 61 = 84
5x = 84 + 61
5x = 145
x = 29
2.-
m∠1 + m∠6 = 180 they are supplementary angles
∠1 = 180 - 143
∠1 = 37
∠1 = ∠ 3 because are vertical angles.
3.-
m∠2 + m∠5 = 180 they are supplementary angles
∠2 + 79 = 180
∠2 = 180 - 79
∠2 = 101
m∠3 = m∠5 they are alternate angles
