Consider the same system of equations:
equation 1: 3x + y = 5
equation 2: 5x – 4y = -3
when you solve for the correct variable, what is the new equation?
= 3 + 4y
o
o
o
x=5 - y
y=-3x + 5
y = 3x - 5

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

3+x

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
