5x + 3y = 38
2x+3y=13
y=?
x=?

The solution to the system of equations is:

Step-by-step explanation:

Given the system of equations

solving the system of equations

Multiply 5x+3y=38 by 2:    10x+6y=76

Multiply 2x+3y=13 by 5:     10x+15y=65

so

now solving 9y = -11 for y

divide both sides by 9

Simplify

For 10x+6y=76 plug in y = -11/9

subtract 6(-11/9) from both sides

Divide both sides by 10

Therefore, the solution to the system of equations is:

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
