Assuming this is a system of equations, here is how to find x. 

2x + 3y = 45
x + y = 10 

Multiply x + y = 10 by 2 so you are able to use the elimination method.

2x + 3y = 45
2x + 2y = 20

Subtract.

y = 25

Now that we've found y, we can plug it in to find x. 

x + 25 = 10

Subtract 25 from both sides.

x = -15

scoray [572]

Answer:

x = 9.8

Step-by-step explanation:

to find x, use pythagorean theorem

a^{2} = c^{2} - b^{2}

a^{2} = 14^{2}  - 10^{2}

a^{2} = 196 - 100

a^{2} = 96

\sqrt{a^2} = \sqrt{96}

a = 9.7979 ⇒ 9.8
