Question

answer the two questions (1)find a number is 5 more than 15 (2)solve -4 (3+x)=8
​

Answer 1

Answer:

1st one answer is 20

Step-by-step explanation:

Because

More than means +

So it is 15 + 5

= 20

Answer 2

(i) We are looking for a new number which is 5 more than 15.

We will get the new number by adding 5 to 15.

We write it down as:

15+5=20

And finally the solution for: What number is 5 more than 15?  It is 20 .

(ii) Answer x = -5

Step by step explanation:

Step 1: Rearrange terms

-4 (3+x)=8

-4(x+3)=8

Step 2: Distribute

-4(x+3)=8

-4x-12=8

Step 3: Add 12 to both sides of the equation

− 4 − 1 2 = 8

-4x-12+12=8+12

Step 4: Simplify

Add the numbers

-4x-12+12=8+12

-4x=8+12

Again add the numbers

-4x=8+12

-4x=20

Step 5: Divide both sides of the equation by the same term

-4x=20

-4x/-4 = 20/-4

Step 6: Again Simplify

Cancel terms that are in both the numerator and denominator

-4x/-4 = 20/-4

x=20/-4

Divide the numbers

x=20/-4

x=-5 (-4 x 5 = 20)

∴x=-5
