Can someone help me pleaseee /// I suck at maths bleh

Here's the solution :

squaring both sides :

here , x is present on both sides and cancel out each other

so, value of x can't be determined. hence the expression has no solution ~

3x + 4y -25 =0 represents the amount of change sianna should recieve

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
