Question

Select the TWO equations that have t = 5 as a solution.

Answer 1

Answer:

Question :-

Select the TWO equations that have t = 5 as a solution.

Required Answer:-

B. 6 × t = 30

D. t + 9 = 14

Explanation :-

➵ Let's substitute the value of t as 5

$A. \: 4 + t = 10$

$4 + 5 = 10$

$9 \: \cancel= 10$

$LHS \: \cancel = \: RHS</p><p>$

so 4 + t = 10 is not the solution of equation.

➵ Now let's try with option B

$B. \: 6 × t = 30$

$6 \times 5 = 30$

$30 = 30$

$LHS = \: RHS$

6 × t is one of the solution of the equation.

➵ Let's try for options C

$C. \: t × 5 = 10$

$5 \times 5 = 10$

$25 \: \cancel = \: 10$

$LHS \: \cancel = \: RHS$

Therefore t × 5 = 10 is not the solution of the equation.

➵Now let's also try with option D

$D. \: t + 9 = 14$

$5 + 9 = 14$

$14 = 14$

$LHS = \: RHS$

so t + 9 = 14 is the solution for the equation.

Therefore the two solutions for the equation are 6 × t = 30 and t + 9 = 14
