Answer:
Friday=$10 Saturday=$20 Sunday=$40
Step-by-step explanation:
On Friday we can estimate that he earnt $10 so twice as many as that is $20 so on Saturday he could of earnt that much. Finally what is 20 half of? 40 so 10+20+40=$70
Simplify both sides of the equation, add 6x to both sides, subtract 48 from both sides, then divide both sides by 70. Your answer would be x= -1
Writing equivalent equations help you solve system of equations because it sets it up for being broken down part by part.
