Given 2x - 3 = 7, what is the value of x?

2x-3=7 /×3

2x=3+7

2x=10 /÷2

x=5

Step-by-step explanation:

2x - 3 = 7                         Add 3 to both sides

2x - 3+3 = 7 + 3                Combine

2x = 10                              Divide by 2

2x/2 = 10/2                       Combine

x = 5

These types of equations all follow the same pattern. The look like

ax + b = c                         You have to isolate the x so add b if b is minus or you subtract b if b is plus. Notice that b was minus in your question. So Add

Now you you have

ax  =  c - b                      That always happens. The x is isolated if you deal with b first. Now all you need to do is divide by a.

x = (c - b)/a

Try a couple

3x -4 = 5                       The answer is 3

5x + 2 = 27                   the answer is 5

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
