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]

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

y = 11

6x + 55 = 7

6x = -48

x = -48

Glenda and Fiero are at a restaurant eating meal that costs $30. They have a discount coupon that gets them 10% off the cost. If

yaroslaw [1]

The cost of meal = $$30$

The tip to the waiter = $8%$ %

Discount = $10%$ %

Cost = $30 + 0.08 * 30 - 0.1 * 30$

Cost = $30(1 + 0.08 - 0.1)$

Cost = $ $$29.4$ 0
