Ответ:
x = 3
Step-by-step explanation:
Step 1 - Expand the brackets:
-2(1 - 5x) = 4 - 4(-2x)
-2 - (-5x) = 4 - (-8x)
-2 + 10x = 4 + 8x
Step 2 - Subtract 8x from both sides:
-2 + 10x - 8x = 4 + 8x - 8x
-2 + 2x = 4
Step 3 - Add 2 to both sides and isolate 2x:
-2 + 2x + 2 = 4 + 2
2x = 6
Step 4 - Divide by two:
2x ÷ 2 = 6 ÷ 2
x = 3
Hope this helps!
