Solve the system of equations.<br> 4x + y = 2<br> x - y=3

Luda [366]

Answer:

x = 1

y = -2

Explanation:

$\bold{\begin{bmatrix}4x+y=2\\ x-y=3\end{bmatrix}}$

Isolate x for 4x + y = 2: x = 2 - y / 4

Substitute x = 2 - y / 4

2 - y / 4 - y = 3

Simplify

2 - 5y / 4 = 3

Isolate y for 2 - 5y / 4 = 3: y = -2

For x = 2 - y / 4 substitute y = -2

x = 2 - (-2) / 4

2 - (-2) / 4 = 1

x = 1

x = 1, y = -2

A pharmacist wishes to mix a solution that is 4% Minoxidil. She has on hand 90 ml of a 1% solution and wishes to add some 6% sol

Yakvenalex [24]

Step-by-step explanation:

remember, 1% = 1/100 = 0.01

4% = 0.04

6% = 0.06

so, we have to find the solution for

90×0.01 + x×0.06 = (90+x)×0.04

with x being the amount needed of the 6% solution.

90×0.01 + x×0.06 = 90×0.04 + x×0.04

90×0.01 + x×0.02 = 90×0.04

x×0.02 = 90×0.03

x = 90×0.03/0.02 = 135 ml

so, we need to add 135 ml of the 6% solution to get in total a 4% solution (90+135 = 225 ml of that).
