Me pueden ayudar a resolver por método de sustitución porfa.<br><br> {5x+7y=-1<br><br> {-3x+4y=-24

disa [49]

Answer:

x = 4 and y = -3

Question;

Me pueden ayudar a resolver por método de sustitución porfa.

Translation: Can you help me to solve by please substitution method.

{5x+7y=-1

{-3x+4y=-24

Step-by-step explanation:

Given the simultaneous equation.

5x+7y=-1 .....1

-3x+4y=-24 .....2

From equation 2, making y the subject of formula.

4y = -24 + 3x

y = (-24+3x)/4 ...... 3

Substituting the equation 3 into equation 1

5x+7((-24+3x)/4) = -1

Multiply through by 4

20x + 7(-24+3x) = -4

20x - 168 + 21x = -4

41x -168 = -4

41x = -4 + 168

41x = 164

x = 164/41 = 4

x = 4

Substituting x = 4 into equation 3

y = (-24+3(4))/4

y = (-24+12)/4

y = -12/4

y = -3

\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{4-1}{7-1}\implies \cfrac{3}{6}\implies \cfrac{1}{2}$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-1=\cfrac{1}{2}(x-1)\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-1=\cfrac{1}{2}x-\cfrac{1}{2}\implies y=\cfrac{1}{2}x-\cfrac{1}{2}+1\implies y=\cfrac{1}{2}x+\cfrac{1}{2}$
