Rearrange ➡ 3 + 9 × (1 - 5r) - (25)

Step 1. Equation ⬇

(3+9 × (1 - 5r )):- 25 = 0



Step 2. Take out the like terms (factors) ⬇

-45r - 13 = -1 × (45 + 13 )

Equation part 2 ➡ -45 - 13 = 0

Add 13 to both sides of the equation ➡ -45=13

Multiply both sides of the equation by (-1 ) : 45r= -13


divide both sides of the equation by 45

r= -0.289

What is the solution? pls help
loris [4]

Answer:

Solve by substitution

[y=5/2x-4]

[y= -x+3]

Substitute y = -x +3

[-x+3=5/2x-4]

Isolate x for -x+3=5/2x-4: x=2

For y = -x+3

Substitute x = 2

y= -2+3

Simplify

y=1

The solutions to the system of equations are:

y=1 x=2
