Answer:
3.1x+2.8z
3.1 over 10x +14 over 15 z
1 over 10 x (3.1x + 2.8z)
4.3x - 1.2z =
43 over 10x - 6 over 5z
1 over 10 x (43x-12z)

Answer:
All real numbers would be the solution
Step-by-step explanation:
2y - 4x =2 and y = 2x + 1
We solve but placing the value of y into the first equation:
2(2x + 1) - 4x = 2
Next we distribute the 2 through the parenthesis:
4x + 2 - 4x = 2
Now we gather like terms:
2 = 2 ( note the 4x and - 4x cancel out)
Since 2 =2 this tells us that all real numbers would work.
