4 (x + 1.2) = 1.5x + 5.2 to solve the equation
4x+4.8=1.5x+5.2
4x-1.5x=5.2-4.8
2.5x=0.4
The solution is x = 0.16
27.5-5x = 12.5
5x=15
x=3
10: 7 * 25 = 0.5x-27:56 to solve the equation, (: is the comparison sign)
56x=7×25×0.5x-7×25×27;
31.5x=4725;
x=150;
If you don't understand this question, you can ask,
X-2 / 15 = 3 / 5 4 / 5x = 28
Yes, 50 points
x-2/15=3/5
x = 3/5 + 2/15
x = 11/15
4/5x=28
x = 28 x 5/4
x = 35
