Answer:
Simplifying
5x + 12 = -13
Reorder the terms:
12 + 5x = -13
Solving
12 + 5x = -13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 5x = -13 + -12
Combine like terms: 12 + -12 = 0
0 + 5x = -13 + -12
5x = -13 + -12
Combine like terms: -13 + -12 = -25
5x = -25
Divide each side by '5'.
x = -5
Simplifying
x = -5

Answer:
the answer is 16
Step-by-step explanation:
25-9=16 pens
Car normally has 4 wheeles
motorcycles normall have 2 wheels
c=cars
m=motorcycles
4c+2m=98
c+m=30
multiply second equation by -2 and add to the original equaiton
-2c-2m=-60
4c+2m=98 +
2c+0m=38
2c=38
divide 2
c=19
sub
c+m=30
19+m=30
m=11
11 motorcycles
19 cars
I think the answer is A 28,4 I hopes this helps
That’s the work and the answers
