What is the solution?

−10=2a−4

a=−7

a=−3

a = 3

a = 7

A = -3

Step-by-step explanation:

you basically just add where the equal sign is and put a negative degree  *for this type of problem* and then divide by whatever number you haven't worked with yet and in this case that is 4 then you get A = -3

-10=2a-4

-10+ -2= -12

-14 / 4= -3

A = -3

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
