Step-by-step explanation:

If you mean the equation

y = 4x + 5

y = x - 4

then yes

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

The angles are supplementary, so x + 5 + 2x -8 = 180. Solve for X. I distributed 2(x -4) to get 2x - 8.

add 3 to both sides
3x = 183
divide by 3 to both sides
x = 61

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given data in the question,

Distance (d) traveled by the horse = 0.5 miles

Time (t) taken by the horse to cover the distance = 1.25 minutes

Then, the speed of the horse will be,

[tex]Speed=\frac{Distance}{Time}[/tex]

s = 0.5/1.25

s = 0.4 miles/minute.
