The equations which has the same value of x as the given equation; Three-fifths (30 x minus 15) = 72 are;
Since the given equation in the task content is;
Three-fifths (30 x minus 15) = 72
The word phrase can be written algebraically as follows;
3/5 ( 30x - 15 ) = 72
The equation can therefore be solved as follows;
(3/5 × 30x) - (3/5 × 15) = 72
= ( 3 × 6x ) - (3 × 3) = 72
= 3 (6x - 3) = 72............. Equivalent expression.
By the distributive property; we have;
18x - 9 = 72..................... Equivalent expression
And by solving for the value of x; we have;
18x = 81
x = 81 / 18
x = 4.5
On this note, the equations which have the same value for x as; Three-fifths (30 x minus 15) = 72 are;
