Does the equation 5x-(7x-1)=-3x+8 has exactly one solution

x=7  so there is one solution

Step-by-step explanation:

5x-(7x-1)=-3x+8

Distribute the minus sign

5x -7x +1 = -3x+8

Combine like terms

-2x +1 = -3x+8

Add 3x to each side

-2x+3x+1 = -3x+3x+8

x+1 = 8

Subtract 1 from each side

x+1-1=8-1

x=7

Yes

Step-by-step explanation:

5x-(7x-1)=-3x+8

5x - 7x + 1 = -3x + 8

-2x + 3x = 8 - 1

x = 7

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
