Question

solve the following equations and verify the solutions: 5(x-1)-2(x+8)=0​

Answer 1

Answer:

5x-5-2x-16=0

3x-21=0

3x=21

x=21/3

x=7

verification

By taking LHS,

5(7-1) -2(7+8)

(5×6)-(2×15)

30-30

0=RHS

hence proved..

Answer 2

$\huge\color{pink}\boxed{\colorbox{Black}{Answer}}$

$5(x - 1) - 2(x + 8) = 0 \\ 5x - 5 - 2x - 16 = 0 \\ 3x - 21 = 0 \\ 3(x - 7) = 0$
