If you were to solve the following system by substitution, what would be the best
xxMikexx [17]
To solve the two equations simultaneously using the substitution method we need to rearrange one of the equation to make either 'x' or 'y' the subject. 

We can try in turn rearranging both equations and see which unknown term would have been easier to solve first

Equation 2x+8y=12

Making 'x' the subject
2x=12-8y , dividing each term by 2
x=6-4y⇒ (Option 1)

Making 'y' the subject
8y=12-2x, multiply each term by 8 gives
y= \frac{12}{8} - \frac{2}{8}x⇒ (Option 2)

Equation 3x-8y=11
Making 'x' the subject
3x=11+8y, divide each term by 3
x= \frac{11}{3}+ \frac{8}{3}y ⇒ (Option 3)

Making 'y' the subject
8y=3x-11, divide each term by 8
y= \frac{3}{8}x- \frac{11}{8} ⇒ (Option 4)

From all the possibilities of rearranged term, the most efficient option would have been the first option, from equation 2x+8y=12 with 'x' as the subject, x=6-4y
