Finally, add all sides together to get 290.

I need help understanding this. SO please help and give explanation

So my understanding from this you have to make it y = mx + b so m stands for the slope there’s different ways to find it as shown in the first picture. I’ll try to make another comment since this only lets me take one picture at a time.

Solve both equations.

lakkis [162]

Equation 1:

Answer:

x = 1.22

Step-by-step explanation:

$\frac{5x-1}{8} -\frac{5-7x}{2} = \frac{3(6-x)}{6}$

$\frac{2(5x-1) - 8(5-7x)}{16} = \frac{3(6-x)}{6}$

$\frac{(10x-2) - (40-56x)}{16} = \frac{3(6-x)}{6}$

$\frac{(10x-2-40+56x)}{16} = \frac{3(6-x)}{6}$

$\frac{(66x-42)}{16} = \frac{3(6-x)}{6}$

$\frac{(66x-42)}{16} = \frac{(18-3x)}{6}$

$(66x-42) \times 6 = (18-3x) \times 16$

$(396x-252) = (288-48x)$

$(396x +48x) = (288+252)$

$444x = (540)$

$x = \frac{540}{444}$

x = 1.22

Equation 2:

Answer:

x = -13.97

Step-by-step explanation:

$\frac{x}{3} - \frac{7(x-2)}{9} = 4- \frac{2x-5}{6}$

$\frac{9x-3(7(x-2))}{27} = 4- \frac{2x-5}{6}$

$\frac{9x-3(7x-14))}{27} = 4- \frac{2x-5}{6}$

$\frac{9x-(21x-42))}{27} = 4- \frac{2x-5}{6}$

$\frac{9x-(21x-42)}{27} = \frac{24 - (2x-5)}{6}$

$\frac{-12x+42}{27} = \frac{-2x+29}{6}$

$(-12x+42) \times 6 = (-2x+29) \times 27$

$(-72x+252) = (-34x+783)$

$(252-783) = (-34x +72x)$

$(-531) = (38x)$

$x =\frac {-531}{38}$

x = -13.97

Find the value of the variable

erik [133]

X+1=y and 3y-7=2x are your two equations.

Substitute x+1 in for y
3(x+1)-7=2x
3x+3-7=2x
x-4=0
x=4

Plug in 4 for x in either equation to solve for y
x+1=y
4+1=y
5=y

x=4 and y=5

Hope I could help!
