Answer:

No solution

Step-by-step explanation:

Two lines, A and B, are represented by the equations given below:

Line A: x + y = 6

Line B: x + y = 4

Solve for x  and y

Multiply Line A equation by -1

-x -y = -6

x + y = 4

-------------------(add both equations)

0 + 0  = -2

0=-2

We arrived at a false statement, so no solution for this system of equations

If the lines cross, there is a solution , which means that there is a y and x value which satisfies both equations. 
since both the equations start with x+y they shoulddd have the same answer if they had crossed. we can tell straight away these lines do not cross because 6=/=4 6 doesnt equal 4. therefore no solution. 
TIP: for the future, if they had crossed, you can use simultaneous equations to find x and y to see if they work in each equation and find a solution ( since they are straight lines there will only be 1 solution, unless they are literally the same line in which case then then they are ALWAYS on top of each other and always have the same values)

Answer:

3x - y = 1

Step-by-step explanation:

This will be the same equation written in a different way'

The original equation is:

y = 3x - 1

0 = 3x - y - 1

3x - y = 1.

What is the solution of the following equation? 2x-5+3x=35
harina [27]

<em>2x - 5 + 3x = 35 </em>

<em>simplify </em>

<em>5x - 5 = 35 </em>

<em>add 5 to both sides </em>

<em>5x - 5 + 5 = 35 + 5 </em>

<em>simplify </em>

<em>5x = 40 </em>

<em>divide both sides by 5 </em>

<em>5x/5 = 40/5 </em>

<em>simplify </em>

<em>x = 8 </em>

<em> </em>

andrezito [222]

Answer:

g(f(4)) = -3

Step-by-step explanation:

f(x)=x-7

g(x) = x

g(f(4))

f(4) = 4-7

f(4) = -3

g(-3) = -3
