Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0​

Step-by-step explanation:

3a + b = 10...eq 1

2a + 4b = 0...eq 2

multiple eq 1 by 4

12a +4b = 40

12a + 4b - 2a -4b = 40

10 a = 40

a = 40/4 = 10

put a =10 in equation

3a + b = 10

3(10) + b = 10

b = -20

hope this will be helpful to you.

plz mark my answer as brainlist pl.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
