The product of 50% and 30 of a number is equal to the difference between the number and 28. Find the number (equation)
Let this number be X;
(50x%)*30=x-28
0.5x*30=x-28
15x=x-28
14x=-28
x=-2
So this number is - 2
1.4 times 5 minus 6x equals 28 equations
1.4×5-6X＝28
7-6X＝28
6X＝7-28
6X＝-21
X＝-21÷6
X＝-3.5
28 times x = 308 is equal to several equations
28x=308
x=308/28
x=11
