Answer 1

QUESTION:

$x - 2y = 0$

$3x + 4y - 20 = 0$

solve for x and Y by substitution method.

ANSWER:

Let;

$x - 2y = 0.......(eq.1)$

$3x + 4y = 20......(eq.2)$

now;

with the help of equation 1.

$x = 2y......(eq.3)$

substituting the value of x of eq.3 in eq. 2

$3(2y) + 4y = 20 \\ 6y + 4y = 20 \\ 10y = 20 \\ y = \frac{20}{10} \\ y = 2$

Putting the value of y in eq. 3

$x = 2y \\ x = 2 \times 2 \\ x = 4$

FINAL ANSWER;

$\huge\fcolorbox{red}{yellow}{x = 4}$

$\huge\fcolorbox{green}{yellow}{ y= 2}$
