Question

What is the value of x in the equation 2.5 x + 10 = x minus 0.5?
–7
–3
3
7

Answer 1

Step-by-step explanation:

Given equation is 2.5x+10=x-0.5

=>2.5x-x=-0.5-10

=>(2.5-1)x=-0.5-10

=>1.5x=-10.5

=>x=-10.5/1.5

=>x=(-105/10)/(15/10)

=>x=-105/15

=>x=-7

The value of x=-7

Check:-

LHS=

2.5(-7)+10

=>-17.5+10

=>-7.5

RHS=

-7-0.5

=>-7.5

LHS=RHS is true for x=-7

Answer 2

Step-by-step explanation:

Here you need to get x on once side, so subtract 1x from both sides and subtract 10 from both sides to get the equation 1.5x=(-10.5). now divide 1.5 from both sides to get x = -7
