Question

1.7 Solve the following equations and check the solutions.

a) 5 - 3(5x + 2) = 4(7 - 3x) + 1.
b) 6x+1/3+1=x-3 /6.​

Answer 1

Answer:

a) 5-3(5x+2)=4(7-3x)+1

2(5x+2)=5(7-3x)

10x+4=35-15x

10x+15x=35-4

25x=31

x=1.24

b) 6x+1/3+1=x-3/6

6x+4/3=x-3/6

6x-x=(-3/6-4/3)

5x=11/6

x= 11/6×1/5

x=330/30

x=11
