I need it step by step

elena-s [515]

Answer:

Step-by-step explanation:

we want y by itself...sooo

y - 19 = - $\frac{6}{10}$ (x - (-5))

y - 19 = - $\frac{6}{10}$ (x+5)

y - 19 = - $\frac{6}{10}$ x - $\frac{6}{2}$

y = - $\frac{6}{10}$ x - 3 +19

y = - $\frac{6}{10}$ x + 16

Solve the system of linear equations by substitution

Bond [772]

Answer:

(-4, 5)

Step-by-step explanation (work shown in attached picture):

1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.

2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.

Since x = -4 and y = 5, the solution is (-4, 5).
