Sole for the indicated variable.
ax+r=7, for x

ax+r=7

Move ax to the other side. +positive ax changes to -negative ax

ax-ax+r=7-ax

r=7-ax

r=7-ax or r=-ax+7 ( same thing) but rearranged

step-by-step explanation:

i dont really.know

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
