Question

solve -18.60 = 2.5x - 2.8

Answer 1

Answer:

= -6.32

Step-by-step explanation:

Combine multiplied terms into a single fraction

−18.6=2.5x-2.8

-18.6=5x/2-2.8

Add  2.8 to both sides

then simplify

-15.8-5x/2

Multiply all terms by the same value to eliminate fraction denominators

then Cancel multiplied terms that are in the denominator

Multiply the numbers

2(-15.8)=5x

-31.6=5x

Divide both sides of the equation by the same term

them simplify

x=-6.32

Answer 2

equation: 18.60 = 2.5x - 2.8
Answer: x = -6.32

Solving:

combine multiplied terms into a single fraction .

-18.6 = 2.5x - 2.8
-18.6 = 5x/2 - 2.8

add 2.8 to both sides of the equation .

-18.6 = 5x/2 - 2.8
-18.6 + 2.8 = 5x/2 - 2.8 + 2.8

simplify .
add the numbers
add the numbers

-15.8 = 5x/2

multiply all terms by the same value to eliminate fraction denominators .

-15.8 = 5x/2
2(-15.8) = 2 • 5x/2

cancel multiplied terms that are in the denominator .

2(-15.8) = 2 • 5x/2
2(-15.8) = 5x

multiply the numbers .

2(-15.8) = 5x
-31.6 = 5x

divide both sides of the equation by the same term .

-31.6 = 5x
-31.6/5 = 5x/5

simplify .
divide the numbers .
cancel terms that are in both the numerator and denominator .
move the variable to the left .

x = -6.32

answer: x = -6.32
