x = M+n+ex=2m-x find x pls help me, №18010031, 10.07.2021 08:29

Step-by-step explanation:

m + n + ex = 2m - x ( add x to both sides )

m + n + ex + x = 2m ( subtract m + n from both sides )

ex + x = 2m - m - n = m - n ( factor out x from each term on the left side )

x(e + 1) = m - n ← divide both sides by (e + 1)

x = M+n+ex=2m-x find x pls help me, №18010031, 10.07.2021 08:29

x = \frac{m-n}{e+1}

Step-by-step explanation:

m + n + ex = 2m - x ( add x to both sides )

m + n + ex + x = 2m ( subtract m + n from both sides )

ex + x = 2m - m - n = m - n ( factor out x from each term on the left side )

x(e + 1) = m - n ← divide both sides by (e + 1)

x = \frac{m-n}{e+1}

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Let the father's age be x and son's be y

10 years before-

Father age=x-10

sons age=y-10

Given,

x-10=10(y-10)

x-10=10y-100

Given present age of father=40

therefore,

x=40

40-10=10y-100

10y-100=30

10y=130

y=130/10

y=13

Therefore present age of son=13years
