Question

-4(2x - 5) = 3(x - 15)

Answer 1

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
