Can someone help me solve this and explain step by step algebraically <br> 1/8x+1/4y=2

mote1985 [20]

Answer:

$x=16-2y$

Step-by-step explanation:

$\mathrm{Subtract\:}\frac{1}{4}y\mathrm{\:from\:both\:sides}$

$\frac{1}{8}x+\frac{1}{4}y-\frac{1}{4}y=2-\frac{1}{4}y$

$\mathrm{Simplify}$

$\frac{1}{8}x=2-\frac{1}{4}y$

$\mathrm{Multiply\:both\:sides\:by\:}8$

$8\cdot \frac{1}{8}x=8\cdot \:2-8\cdot \frac{1}{4}y$

$\mathrm{Simplify}$

$x=16-2y$

Final Answer: $x=16-2y$
