Let's solve your equation step-by-step.

$2x-3x+5=18$

Step 1: Simplify both sides of the equation.

$2x-3x+5=18\\2x + -3x + 5 = 18$

$( 2x + -3x ) + ( 5) = 18$ (Combine Like Terms)

$-x + 5 = 18\\-x + 5 = 18$

Step 2: Subtract 5 from both sides.

$-x + 5 - 5 = 18 - 5 \\-x = 13$

Step 3: Divide both sides by -1.

$\frac{-x}{-1} = \frac{13}{-1} \\x = -13$

Answer : $\boxed {x = -13}$

A scientist has saline solutions with concentrations of 4% and 14% . He wants to mix some of each solution to get 65 milliliters

Komok [63]

Let volume of 4% solution = x and of 14% be y

them x + y = 65........(1) also using the actual weights of salt:-

0.04x + 0.14y = 65*0.06 = 3.9

multiplying the above equation by -25 we have

-x - 3.5y = -97.5 adding this to equation (1)

--2.5y = -32.5
y= 13

and x = 65 - 13 = 52

so we need 13 mls of the 14%, and 52 mls of the 4% solution.
