Answer:

Add -4x to both sides--> 6x+9=4x-3 and 2x+9=-3

multiply both sides by -1/4 --> -4(5x+7)=-18 and 5x-7=4.5

multiply both sides by 1/4--> 12x+4=20x+24 and 3x+1=5x+6

multiply both sides by -4--> -5x/4=4 and 5x=-16

add -4 to both sides--> 8-10x=7+5x and 4-10x=3+5x

Kendra lost one half of her allowance but her mother gave her four more dollars now she has $9 how much was her allowance

garri49 [273]

10 dollars because her mom gave her 4. Subtract her total of 9 dollars she has by 4 from her mom. That is 5, however you need to multiply by 2 because she lost one half of it.
