3x - 31 = x + 59

Let's solve your equation step-by-step.

3x−31=x+59

Step 1: Subtract x from both sides.

3x−31−x=x+59−x

2x−31=59

Step 2: Add 31 to both sides.

2x−31+31=59+31

2x=90

Step 3: Divide both sides by 2.

2x

Step-by-step explanation:

3x - 31 = x + 59

Both side -x

3x-x-31=x-x+59

3x-x -31=59

Both side +31

2x-31+31=59+31

2x=90

Both side divide 2

x=45

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
