### Solution

a

$x15 =25$

MultEqn$LHS⋅x=RHS⋅x$

$15=25x$

DivEqn$LHS/25=RHS/25$

$2515 =x$

RearrangeEqnRearrange equation

$x=2515 $

ReduceFrac$ba =b/5a/5 $

$x=53 $

WriteDecWrite as a decimal

$x=0.6$

b

$2x18 =6$

MultEqn$LHS⋅2x=RHS⋅2x$

$18=6⋅2x$

MultiplyMultiply

$18=12x$

RearrangeEqnRearrange equation

$12x=18$

DivEqn$LHS/12=RHS/12$

$x=1218 $

ReduceFrac$ba =b/6a/6 $

$x=23 $
