Multiply the first bracket by -4
Multiply the second bracket by 3
-4(2x - 5) = 3(x - 15)
-4(2x)-4(-5)= 3(x)+3(-15)
-8x+20= 3x-45
Move 3x to the other side. Sign changes from +3x to -3x.
-8x-3x+20= 3x-3x-45
-11x+20= -45
Move +20 to the other side. Sign changes from +20 to -20.
-11x+20-20= -45-20
-11x= -65
Divide by -11
-11/-11x= -65/-11
x= 65/11 or x= 5 10/11
Answer: x= 65/11 or x= 5 10/11
