What’s the question theirs nothing
Answer:
x = 1/5
y = 6
Step-by-step explanation:
System:
{5x + y = 7
{20x + 2 = y
First equation:
5x + y = 7 -> y = -5x + 7
Plug into second equation:
20x + 2 = -5x + 7
Subtract 2 from both sides:
20x = -5x + 5
Add 5x to both sides:
25x = 5
Divde both sides by 25:
x = 5/25 -> 1/5
~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Come back to the first equation:
5x + y = 7
Plus in our x:
5(1/5) + y = 7
Multiply:
1 + y = 7
Subtract 1 from both sides:
y = 6

She has 630 blue beads and 45 red beads. Equation is x + 14x = 675
The first step for solving this expression is to write the division as a fraction.
x +

× x
Calculate the product.

Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:

Now multiply the terms with the same base by adding their exponents.

Finally,, add the numbers together to get your final answer.
x +
