First of all, distribute the product of the two parentheses:

8(7x-1)+4(x+5) = 8\cdot7x - 8\cdot 1 + 4\cdot x + 4 \cdot 5 = 56x-8+4x+20

Sum like terms:

60x +12

Is 5 + 3x1 - x) equivalent to 8 – 8x?
nalin [4]

Answer:

if there is no number in front of a variable, it is understood to be a one. so 1-x would basically be 1-1. this cancels out the x, making it impossible for the equivalent equation to be 8 - 8x
