Find solutions to the linear equation y=−10x+30.

1 answer:

4 0

Answer: x=-y-30/10

1) subtract 30 from both sides

y−30=−10x

2) divide both sides by -10

-y-30/10=x

3) switch sides

x=-y-30/10

Answer:

$\frac{7}{11}$

Step-by-step explanation:

We require 2 equations with the repeating digits (63) placed after the decimal point.

let x = 0.636363..... (1) multiply both sides by 100

100x = 63.6363... (2)

Subtract (1) from (2) thus eliminating the repeating digits

99x = 63 ( divide both sides by 99 )

x = $\frac{63}{99}$ = $\frac{7}{11}$ ← in simplest form
