Question

(b) Solve 8x - 7 = x and verify the correctness of the solution.

(c) Solve 5y +3 = 3y - 4 and verify the correctness of the solution.
​

Answer 1

Step-by-step explanation:

b) 8x-7=x

8x-x=7

7x=7

x=7/7

x=1

verifying: 8(1)-7=1

8-7=1

1=1

c) 5y+3=3y-4

5y-3y=-3-4

2y=-7

y=-7/2=-3.5

verifying: 5(-3.5)+3=3(-3.5)-4

-17.5+3=-10.5-4

-14.5=-14.5

Answer 2

Answer:

b) 8x-7= x

7x. = 7

x. = 1

ᏉᎬᏒᎥfᎽ:

L:H:S:

8.1 -7 = 1

R:H:S:

x=1

hence prooved.

c) 5y +3= 3y-4

2y. = -7

y. = -7/2

ᏉᎬᏒᎥfᎽ:

L:H:S:

5y+3= 5.(-7/2)+3= -35/2+3= -29/2

R:H:S:

3.(-7/2)-4= -29/2

hence prooved.

hope it helps ✨✨____!!!
