Using the Addition Method, solve for y in the following system of linear equations: 4x – 2y = 6 2x + y = 7
Lady_Fox [76]

Answer:

y = 2

Step-by-step explanation:

Addition Method:

4x - 2y = 6

2x + y = 7

-2(2x + y) = -2(7)

4x - 2y = 6

-4x - 2y = -14

-4y = -8

y = 2

Substitution Method:

4x - 2y = 6

2x + y = 7

-2y = 6 - 4x

2y = 4x - 6

y = 2x - 3

2x + (2x - 3) = 7

4x - 3 = 7

4x = 10

x = 2.5

2(2.5) + y = 7

5 + y = 7

y = 2

ted wants to buy a skateboard that costs $59.00, but is on sale for 30% off. How much money will he save
STatiana [176]

Answer:

$17.70

Step-by-step explanation:

Hi,

What you want to do is to find 30% of $59

First, you convert 30% into decimal form by dividing it by 100

30%=0.3


Next, you want to find 30% of 59, so what you do is you take the new decimal form and multiply it by 59

0.3×59=17.7


Ted is saving $17.70
