Question

Please solve these equations!

Answer 1

Explanation:

`2x+4y=154`

One of multiple solutions is

x = 75

y = 1

For a specific value of x and y, at least one other linear equation of two variables is required, so you would have a system of equations of two variables.

Hope this helps

Answer 2

y= -1.2x+38&1/2

x=-2y+77

Explanation:

solving for y

2x+4y-31=123

move them all to the right except for y

4y=-2x+123+31

4y=-2x+154

divide by the coefficient of y

`y=-1/2x+38(1)/(2)`

the answer for y: y= -1.2x+38&1/2

now for x

2x+4y-31=123

move them to the right except for x

2x=-4y+154

divide them

x=-2y+77
