Answer:

m∠Y = 50°

Step-by-step explanation:

let 'm' = m∠Y

m∠S + m∠Y = 90 (complementary)

5m - 210 + m = 90

6m = 300

m = 50

Solve by substitution <br> 1. 6x+ 5y=7 x-y=3<br> 2. 3a +2b =4 2a + b=6<br> 3. 2x + y= 4 4x -y=2
Juli2301 [7.4K]

Answer:

1. y = 11

x = -48

2. a =8

b= -10

3. x= 1

y= 2

Step-by-step explanation:

1 . 6x + 5y = 7

x-y= 3

6x+5y = 7

6x-6y =18

-1y = - 11

6x + 5y = 7

y = 11

6x + 55 = 7

6x = -48

x = -48
