Jason’s age is 3 times shauna’s present age. in 4 years’ time the sum of their ages will be 56 years. find there present age.

Jason -- 36

Shauna -- 12

Step-by-step explanation:

This question in set to the future 4 years so in order to actually solve it, we need to subtract the years to the present. The number of years to subtract is 8 to account for both people's combined age.

so

x -- shaunas age

3x + x = 56 -8

4x = 48

x= 12

Therefore Shauna is 12 years old. Because Jason is three times Shauna's age,  he is 36

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
