3x+7-6=(8/7)-0<br>Value of x?

ArbitrLikvidat [17]

Answer:

$\boxed{\sf x = \dfrac{1}{21}}$

Explanation:

$\rightarrow \sf 3x+7-6= \dfrac{8}{7} - 0$

simplify the following

$\rightarrow \sf 3x+1= \dfrac{8}{7}$

subtract 1 from both sides

$\rightarrow \sf 3x+ 1 -1= \dfrac{8}{7} - 1$

simplify the following

$\rightarrow \sf 3x= \dfrac{1}{7}$

multiply both sides by 1/3

$\rightarrow \sf 3x \cdot \dfrac{1}{3}= \dfrac{1}{7}\cdot \dfrac{1}{3}$

simplify the following

$\rightarrow \sf x = \dfrac{1}{21}$

Please help I don’t know the answer :(

gogolik [260]

Answer:

When x=8, y=-6. When x=10, y=0

Step-by-step explanation:

$y=3x-30\\x^2+y^2=100$

You can plug the given y value into the second equation to get:

$x^2+(3x-30)^2=100\\x^2+9x^2-180x+900=100\\10x^2-180x+800=0\\10(x^2-18x+80)=0\\10(x-8)(x+10)=0\\x= 8, 10\\y= -6, 0$

Hope this helps!
