Answer:

x = 10

Step-by-step explanation:

Coordinate pairs are given in the form (x,y)

So, since (x,3/4) is a solution, we can say

y = 3/4

Now we plug in y = 3/4 into the equation and solve for x:

$3x + 8y - 36 = 0\\3x + 8(\frac{3}{4}) - 36 = 0\\3x + \frac{24}{4}-36=0\\3x+6-36=0\\3x=36-6\\3x=30\\x=\frac{30}{3}\\x=10$

So, the value of x is 10

The solution is x = 10

Find x, if 3x − 5(y + x ) ^2 = 16 and 4x + 2(y + x )^ 2 = 30

lana66690 [7]

Answer:

x = 7

Step-by-step explanation:

Start by solving for $(y+x)^2$ which is a common expression for both equations. Then in the first equation:

$3\,x5\,(y+x)^2=16\\3x-16=5\,(y+x)^2\\(y+x)^2=\frac{3\,x-16}{5}$

and in the second equation:

$4\,x+2\,(y+x)^2=30\\2\,(y+x)^2=30-4\,x\\(y+x)^2=15-2\,x$

Now we make the two $(y+x)^2$ expressions equal so we get:

$\frac{3\,x-16}{5} =15-2\,x\\3\,x-16=75-10\,x\\13\,x=75+16\\13\,x=91\\x=7$
