Which of the following equations has no solution? 5x + 20 – x = 7(3 + x) – 3x
x + 20 – 5x = 7(3 + x) – 3x
5x + 21 – x = 7(3 + x) – 3x
5x + 20 – 7x = 7(3 + x) – 3x​

The isosceles triangle has two sides of equal length, a, that sre longer than the length of the base ,b. the equation 2a+b=15.7 can be used to find the sides length. if one of the longer sides is 6.3 centimeters what is the length of the base
