Let's go step-by-step ⇒
[tex]\frac{10x + 4}{7} = 8[/tex]
= [tex](\frac{7}{1})\frac{10x+4}{7} = \frac{8}{1}(\frac{7}{1})[/tex]
= [tex]10x+4=56[/tex]
= [tex]10x = 52[/tex]
= [tex]x = 5.2[/tex]
Your answer is x = 5.2

solve the simultaneous equations 4x-3y=19 and 2x+3y=23
Answers
Step-by-step explanation:
[tex] \underline{ \underline{ \text{Solution}}} : [/tex]
[tex] \sf{4x - 3y = 19}[/tex] ••••• equation ( i )
[tex] \sf{2x + 3y = 23}[/tex] ••••• equation ( ii )
The coefficients of y are the same in both equation but the sign of 3y of equation ( i ) differs from the equation ( ii ). So , we add one equation from the other to eliminate 3y.
Adding equation ( i ) and ( ii ) , we get :
[tex] \sf{4x \: \cancel{ - 3y}} = 19[/tex]
[tex] \sf{2x \: \cancel{ \: + 3y}} = 23[/tex]

⟿ [tex] \boxed{ \sf{x = 7}}[/tex]
Now , substituting the value of x in equation ( ii ) , we get ( Remember : you can substitute the value of x in any of the equation ) :
[tex] \sf{2x + 3y = 23}[/tex]
⟿ [tex] \sf{2 \times 7 + 3y = 23}[/tex]

Someone help me do this please. I included a picture.
Answers
Answer:
52° and 128°
Step-by-step explanation:
The sum of the angles in a triangle is 180°
So to find the angles, the easiest thing to do is to use that fact.
There is one angle missing in the triangle shown, so to find it you need to subtract (5x-2)° from 180° since the angle is located on a line.
Simplifying that, you get 180°-(5x-2)°.
Now you can use the fact at the top of these instructions.
So you get the equation: 180°=2x°+76°+180°-(5x-2)°
Solving this equation, you get x=26
Plug x into the values that have x in the picture, and you get 52° and 128°

Answers
Answer:
We conclude that -1 = 0 is false, therefore the system of equations has no solution.
Step-by-step explanation:
Given the system of equations
y = – 4x + 6
y = – 4x + 5
solving the system of the equations
[tex]\begin{bmatrix}y=-4x+6\\ y=-4x+5\end{bmatrix}[/tex]
Substitute y = -4x+5
[tex]\begin{bmatrix}-4x+5=-4x+6\end{bmatrix}[/tex]
Refine – 4x + 5 = – 4x + 6
-1 = 0
FALSE!
