Step-by-step explanation:
Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6

{ y = 4 - x
y = x - 4
Subsititute y = x - 4
[ ( x - 4 )] = 4 - x ]
isolate x for ( x - 4 ) = 4 - x
x = 4
For y = x - 4
Subsititute<span> x = 4
</span>
y = 4 - 4
y = 0
Solution
x = 4 and y = 0
hope this helps!
