Carlos has 7 times as many red toy cars as blue toy cars. He has 56 total cars. How many more red cars does he have?
1 answer:
let x = blue cars
so 7x = red cars
x +7x = 56
8x = 56
x = 56/8 =7 blue cars
7*7 =49 red cars
49-7 =42 more red cars

<h2>
x=2</h2>
Step-by-step explanation:
Isolate x
3x + 4x - 8 = 6
+8 +8
3x + 4x = 6 + 8
Simplify
3x + 4x = 6 + 8
7x = 14
Divide both sides by 7
7x/7 = 14/7
x = 2
