Ответ:
x = 1/2
Step-by-step explanation:
Ответ:
x = 0.5
Step-by-step explanation:
2(4x+2)=4x-12(x-1) (by PEDMAS, we deal with the parentheses first by using the distributive property)
4x(2)+2(2)=4x+ x(-12) -1 (-12)
8x + 4 = 4x - 12x +12 (simplyfy each side)
8x + 4 = - 8x +12 (add 8x to both sides)
8x + 4 + 8x = 12
16x + 4 = 12 (subtract 4 from both sides)
16x = 12 - 4
16x = 8 (divide both sides by 16)
x = 8/16
x = 0.5
