1/5x-2/3y=30 when y=15

dolphi86 [110]

Answer:

Step-by-step explanation:

Step 1: Set y to 15 and solve

$\frac{1}{5}x - \frac{2}{3}*15=30$

$\frac{1}{5}x-10=30$

Add 10 to both sides

$\frac{1}{5}x-10+10=30+10$

$\frac{1}{5}x=40$

Multiply both sides by 5

$\frac{1}{5}x*\frac{5}{1}=40*\frac{5}{1}$

$x=200$

Answer: $x=200$

\begin{aligned} &2x+7y=1 \\\\ &y=4x -8 \end{aligned}

Lina20 [59]

Answer:

Step-by-step explanation:

hello :

2x+7y=1 ...(*)

y=4x−8...(**)

(4;8) means x= 4 and y= 8

put this values in (*) and(**) :

2(4)+7(8) =1 62=1 false

8=4(4)-8 8=8 true

so :(4;8) is not solution for this system.
