Question

Solve:
7(5 - 5x) = 25-4(2 - 2x)​

Answer 1

Answer:

x = 1

Step-by-step explanation

7(5-5x) = 25-4(2-2x)

35 - 35x = 50 - 50x - (8 - 8x)

I have not minus 25 with 4 becuase its rule of mathematics that we should do brackets first

35-35x = 50-50x-8+8x

Now Arrange

35 - 50 + 8 = -50x + 8x + 35x

-7 = -7x

-7/-7 = x

1 = x

x=1

Hope it helps you!!!!

Answer 2

Answer:

x=7

Step-by-step explanation:

7(5-5x)=25-4(2-2x)

35-35x=21(2-2x)

35-35x=42-42x

-35x-42x=42+35

-11x=77

x=77/11

x=7
