Answer:

(0,-5)

Step-by-step explanation:

By the Graph Method, for single solution the solution will be the intersection point of these lines. Each line is defined by an equation. The first one: x+y=-5 and the Second one: -3x-y=5

So, (0,-5) is the solution.

Combine 2y+1x=40 and y=2x using substitution
fomenos

2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution

<em><u>Solution:</u></em>

Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method

The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.

<em><u>Given equations are:</u></em>

2y + 1x = 40 -------- eqn 1

y = 2x ----------- eqn 2

We can substitute eqn 2 in eqn 1

Which means, substitute y = 2x in place of y in eqn 1

2(2x) + 1x = 40

4x + 1x = 40

5x = 40

x = 8

From eqn 2,

y = 2(8)

y = 16

Thus by combining using substitution method we found the solution
