Help me do this.
No answers please.
Just tell me basically what to do and stuff.

1) Solve and check each of the following.
a) 0.4x = 5.58 – 0.2x
b) 7.2 + 2.3x = 3.2x
c) x/6 – 9/2 = 2x/3
d) 3/2 m = m + 7
e) (x – 3)/2 = 10
f) 1.4m = 1.5m – 0.57

2) Solve and check each of the following.
a) (1/2)x – 1 = (1/4)x + 3/4
b) 1.3m + 64.2 = 2.7m + 12.82
c) 5n – 6.4 = 3n + 2.6
d) (1/2)n – 3 = 4 + (2/3)n
e) (1/4)x + (1/3)x = x + 1/6
f) 1.2m – 17 = 8 + 0.7m

You get the idea...

... if you don't, grab a textbook.

this looks like 2 unit general maths. dont u have a graphics calculator? type it into that and it should solve

And note that non-CAS GDCs don't show how an equation is solved (unless you're using the step functions from TI's later calculators) and neither would that really help with such simple examples.

im doing 3 unit math. normally this takes like 2 secs. just watever u do to one side of the equation u goto do to the other side. and for this just get x to one side then simplify it to 1x.
