Question

4 ( 2x - 3 ) = 2 ( 3x - 1 )

Answer 1

Distribute 4 and 2 to (2x-3) and (3x-1) respectively

8x-12 = 6x-2

Then transpose 6x to the left side and -12 to the right

8x-6x=-2+12

2x=10

x=5

Answer 2

How do you solve this system of equations ?
3x + y = 11
y = x + 3

Answer 3

Since

y=x+3, you can substitute that value of y into the first equation (3x+y=11)
This will give
3x+(x+3)=11
4x+3=11
4x=11-3
4x=8
x=2
