<h2>(1, 4)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}2x=-y+6&(1)\\-4x+3y=8&(2)\end{array}\right\\\\(1)\\-y+6=2x\qquad\text{subtract 6 from both sides}\\-y=2x-6\qquad\text{change the signs}\\y=6-2x\\\\\text{substitute it to (2):}\\\\(2)\\-4x+3(6-2x)=8\qquad\text{use the distributive property}\\-4x+(3)(6)+(3)(-2x)=8\\-4x+18-6x=8\qquad\text{subtract 18 from both sides}\\-10x=-10\qquad\text{divide both sides by (-10)}\\x=1\\\\\text{put the value of x to (1):}\\\\y=6-2(1)\\y=6-2\\y=4

Please help, it’s due today :)

Answer:

x =5

Step-by-step explanation:

We can use ratios for the side lengths

9              x

--------- = -----------

9+18       x+10

Using cross products

9 (x+10) = x * (9+18)

Distribute

9x+90 = x*27

9x+90 = 27x

Subtract 9x from each side

9x-9x+90 = 27x-9x

90 = 18x

Divide each side by 18

90/18 = 18x/18

5 =x
