Answer:
y=2x-5
Step-by-step explanation:
First simplify: y-1=2x-6
y-1=2(x-3)
First simplify and distribute everything.
<u>y-1=2x-6</u>
So, x equals 2 because it got distributed into the numbers inside the parenthesis. Same with the 2 and -3. They multiplied to become -6.
Since it's y-1=2x-6, you can simplify it even more so the -1 goes to the other side and turns into positive 1.
<u>y - 1 (+ 1) = 2x -6 (+ 1)</u>
-1(+1)=0 which leaves just the variable y on the <em><u>left side</u></em>.
-6(+1)=-5 which leaves 2x-5 on the <em><u>right side</u></em>.
This results in y=2x-5. Hope this helped ;)
<h2>Решение (а):</h2>
Чтобы найти значение x, воспользуемся перекрестным умножением.
Что значит ,
= 2 × 30 = 5 × х
= 2 × 30 = 5x
= 60 = 5x
= х = 60 ÷ 5
= х = 12
Следовательно, 2/5 = 12/30.
<h2> Решение (б):</h2>
Чтобы найти значение x, воспользуемся перекрестным умножением.
Что значит ,
= 30 × 8 = 48 × х
= 30 × 8 = 48x
= 240 = 48x
= х = 240 ÷ 48
= х = 5
Следовательно, 5/8 = 30/48 .
