For the equation 2x + 3 = 4x – 3:
a. How many solutions does it have?
b. How do you know?

a) one solution, x=3

b) see below

Step-by-step explanation:

2x+3=4x-3

2x=6

x can only be=3

Step-by-step explanation:

2x + 3 = 4x - 3

-2x + 3 = -3

-2x = -6

x = 3

a. one solution

b. used the multi step equation

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
