8m - 5n + 2m + 6n =Simplifying 8m + -5n + 2m + 6n = 0 Reorder the terms: 8m + 2m + -5n + 6n = 0 Combine like terms: 8m + 2m = 10m 10m + -5n + 6n = 0 Combine like terms: -5n + 6n = 1n 10m + 1n = 0 Solving 10m + 1n = 0 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1n' to each side of the equation. 10m + 1n + -1n = 0 + -1n Combine like terms: 1n + -1n = 0 10m + 0 = 0 + -1n 10m = 0 + -1n Remove the zero: 10m = -1n Divide each side by '10'. m = -0.1n Simplifying m = -0.1n.

John’s father is 5 times older than John and John is twice as old as his sister Alice. In two years time, the sum of their ages

oksano4ka [1.4K]

Answer:

John’s age is 8 years

Step-by-step explanation:

Let

x -----> John’s father's age

y -----> John’s age

z -----> John’s sister's age

we know that

$x=5y$ -----> equation A

$y=2z$

$z=y/2$ -----> equation B

$(x+2)+(y+2)+(z+2)=58$

$x+y+z+6=58$

$x+y+z=52$ -----> equation C

Substitute equation A and equation B in equation C and solve for y

$5y+y+y/2=52$

Multiply by 2 both sides to remove the fraction

$10y+2y+y=104$

$13y=104$

$y=8$

<em>Find the value of x</em>

$x=5(8)=40$

<em>Find the value of z</em>

$z=8/2=4$

therefore

John’s father's age is 40 years

John’s age is 8 years

John’s sister's age is 4 years
