We can use the substitution method to solve this problem.

The second equation is \sf y=2x, so we can plug in 2x for 'y' in the first equation:

\sf 5x-2y=3

\sf 5x-2(2x)=3

Multiply:

\sf 5x-4x=3

Combine like terms:

\sf x=3

This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:

\sf y=2x

\sf y=2(3)

Multiply:

\sf y=6

This is the y-value of our solution. So our entire solution is (3, 6).

Find the value of x that makes this equation true, just write a number for your answer. Use / for writing fractions
Tcecarenko [31]

Answer:

1/15

Step-by-step explanation:

The first thing to do is to change both denominators so that they're the same. In this case, that would be 15.

Then, whatever you do to the denominator, you must also do to the numerator.

\frac{9}{15} + x = \frac{10}{15}

X = 1/15
