So in equations you want to do the same thing to both sides so that the equation will stay equal

when dealing with one unknown number (m) try to get them all on the same side

0.6m+3=2m+0.2
I usually like positive unknowns so
subtract 0.6m from both sides
3=1.4m+0.2
subtract 0.2 from both sides
2.8=1.4m
divide both sides by 1.4
2.8/1.4=2=x

if dividing by decimals move the decimal either round the decimals up or down then divide. or multiply them by the 10 to the same power then divide.

x=2

M=2 is the answer, because you just combine like terms and get -1.4m=-2.8. divide both by two and get m=2

Step-by-step explanation:

here is the complete question :

Toni invests money into an account which pays a fixed rate of compound interest each year. The total value, £V, of her investment after t years is given by the formula:

V = 1350 x 1.04^t

Answer questions a & b

a - How much money did Toni invest in pounds

b - What rate of compound interest is paid each year

the formula for calculating compound interest is given by :

V = P (1 + r)^t

P = Present value -= amount invested = 1350

R = interest rate = 4%

N = number of years = t
