Which value from {2,5, 15, 50}, makes the equation true?<br> n - 5 = 10<br> 50

Zarrin [17]

Answer:

15 makes the equation true

Step-by-step explanation:

Data :{2.5.15.50}

Equation : $n-5=10$

We are supposed to find which value from the data satisfies the given equation

So, Substitute n = 2

$n-5=10\\2-5=10\\-3 \neq 10$

Substitute n = 5

$n-5=10\\5-5=10\\0 \neq 10$

Substitute n = 15

$n-5=10\\15-5=10\\10=10$

Substitute n = 50

$n-5=10\\50-5=10\\45 \neq 10$

Hence 15 makes the equation true

Solve the equation. Check your solution, if possible. 2(x + 4) = -5x + 1

Nonamiya [84]

$2(x + 4) = -5x + 1 \\ 2x + 8 = - 5x + 1 \\ 2x + 5x = 1 - 8 \\ 7x = - 7 \\ x = \frac{ - 7}{7} \\ x = - 1 \\ \\ check \\ 2( - 1 + 4) = - 5 \times ( - 1) + 1 \\ - 2 + 8 = 5 + 1 \\ 6 = 6$
answer is x= -1
