Question

Verify that if x = -3, is a solution of the linear equation 10x + 7 = 13 – 5x.​

Answer 1

Answer:

x= -3

10x + 7 = 13-5x

10(-3)+7=13-5(-3)

-30+7=13-(-15)

-23=13+15

-23=28

-23 is not equals to 28.

So, LHS is not equals to RHS.

Answer 2

Answer:

Hey mate,

• LHS = 10x +7[ where x = -3]
• 10*-3 +7
• -30+7= -23.

• RHS = 13 - 5x [where x= -3]
• 13- 5*-3
• 13 - (-15) = 13+15 = 28.

Hence, LHS≠RHS.

DROP SOME THANKS..XD
